shortcut: FAQ

O básico[edit]

Cal son as diferenzas entre MediaWiki, Wikimedia, Wikipedia e wiki?[edit]

Esta é unha pregunta común; por favor ver Diferenzas entre Wikipedia, Wikimedia, MediaWiki, e wiki para unha resposta detallada.

Quero usar unha instancia de MediaWiki (baleira). Teño permiso?[edit]

MediaWiki é software libre: isto quere dicir que podes usalo para calquera propósito sen impedimentos legais. Ademais, as súas condicións de licenza aplícanse só ó software en si. Isto significa que aínda que moitas wikis licenzan o seu contido baixo unha licenza permisiva, ti non estás obrigado a licenciar o contido da túa wiki en ningún xeito particular. Naturalmente, dado que o proxecto se fundou para apoiar sitios coma Wikipedia, animámoste a licenciar os textos que escribas baixo unha licenza libre, aínda que, en resumo, non es obrigado a facelo.

If you wish to alter or amend the software itself, in general, you are permitted to, but there are some restrictions and you should consult the full text of the GNU GPL version 2 for details. Xa que MediaWiki é proporcionado libre de cargo, non hai ningunha garantía, na medida na que o permita a lei aplicábel.

Instalación e configuración[edit]

Onde descargo MediaWiki?[edit]

Preme aquí para descargar a última versión estábel de MediaWiki. Os ficheiros son fornecidos nun ficheiro .tar ou .gz. MediaWiki Tamén pode ser obtido directamente do noso repositorio Git.

Como instalo MediaWiki?[edit]

A instalación do MediaWiki precisa arredor de 10 ou 30 minutos, e implica descarga/copia de ficheiros mais correr un script instalador para configurar o programa. Mira a Guía de instalación, onde tamén atoparás os requisitos mínimos do sistema.

Como instalo MediaWiki usando un paquete?[edit]

Moitas distribucións de Linux proporcionan MediaWiki nun formato empaquetado para esa distribución. O equipo de desenvolvemento do MediaWiki remítete á túa distribución Linux para asistencia coa instalación, configuración ou uso. As comunidades individuais e empresas que manteñen tales paquetes terían que proporcionar instrucións de instalación.

Date conta que as distribucións de terceiros poden ser versións máis vellas, así que pon atención na información de compatibilidade para directrices e extensións.

Podo instalar máis de unha wiki nun servidor usando MediaWiki?[edit]

É posíbel instalar máis de unha wiki nun servidor tendo en conta que:

Teñas unha base de datos diferente para cada wiki Ou Teñas un prefixo de base de datos diferente para cada wiki (para Postgres, podes acadar un efecto similar usando diferentes esquemas e usuarios)

Para información destas opcións, mira $wgDBname e $wgDBprefix respectivamente.

Para información sobre como montar unha familia de wikis, mira o Manual:Wiki family.

For information on an alternative way of setting up more than one wiki using the same server, database and source, see Steve Rumberg's (archived version) excellent exposé and additional comments from users.

MediaWiki traballa co modo_seguro habilitado?[edit]

Si, mais só de xeito limitado. Mira Safe mode para información.

O MediaWiki require acceso por consola?[edit]

O acceso por consola (SSH) non se precisa para instalar MediaWiki, mais é altamente recomendábel. Sen acceso á consola, mesmo pode ser difícil para ti facer unha copia de seguridade da túa wiki, ou actualizar a unha versión nova. Algunhas tarefas de mantemento non son completamente posíbeis sen acceder á consola. Moitos das extensións traballan mellor accedendo por consola.

Como instalo extensións?[edit]

Mira Manual:Extensions para información sobre como instalar e escribir extensións. Mira a Category:Extensions para atopar extensións existentes.

Como engado espazos de nomes extra?[edit]

Mira Creando un espazo de nomes personalizado.

Como habilito a subida de ficheiros?[edit]

A subida de ficheiros é unha característica usada decote en MediaWiki, mais está inhabilitado por defecto en tódalas versións actuais publicadas. Para habilitala, primeiro fai o cartafol para subir (por defecto imaxes) con permisos de escrita para o servidor web (chmod -R 777 ./Imaxes ou deixa que o usuario Apache escriba nel, etc.) Entón pon $wgEnableUploads a true en LocalSettings.php (P.ex. "$wgEnableUploads = true;"). Se tes un reporte de erro "fallo de mkdir" cando tentas subir, probabelmente quere dicir que tes un problema de permisos.

Como habilito fórmulas matemáticas embebidas?[edit]

MediaWiki deixa embeber fórmulas matemáticas. Ver Extension:Math para instrucións completas de configuración.

Como podo estabelecer a zona horaria para a miña MediaWiki?[edit]

' Ver: Manual:Timezone

Como purgo a caché dunha páxina?[edit]

Para purgar purga a caché dunha páxina, como cando se fan cambios á barra de navegación, engade &action=purge ó cabo da URL da páxina dinámica.

Ex.: Http://www.mediawiki.org/w/index.php?title=Main_Page&action=purge

Ou ?action=purge ó cabo da forma curta da URL da páxina:

Ex.: http://www.mediawiki.org/wiki/Main_Page?action=purge

Ver tamén: Manual:PurgeManual:Purge, Manual:Parameters to index.phpManual:Parameters to index.php

Como inhabilito completamente a caché?[edit]

Engade no teu ficheiro LocalSettings.php as liñas seguintes:

$wgEnableParserCacheManual:$wgEnableParserCache = false;
$wgCachePagesManual:$wgCachePages = false;

Como permito a carga de formatos adicionais?[edit]

MediaWiki require que os formatos de ficheiro permitidos para subir, sexan especificados usando a directiva de configuración $wgFileExtensions . Normalmente esta directiva está situada en LocalSettings.php no cartafol raíz da túa instalación MediaWiki.

Por exemplo, para estender o permiso de subida a ficheiros PDF, engade o seguinte a LocalSettings.php:

$wgFileExtensions[] = 'pdf';

Para estender o permiso de subida a máis dun tipo de ficheiro, usa a seguinte sintaxe

$wgFileExtensions = array_merge($wgFileExtensions, array( 'pdf', 'txt', 'mp3' ));
Ver tamén: Manual:Configuring file uploadsManual:Configuring file uploads

"O ficheiro é corrupto ou ten unha extensión non válida"[edit]

Algúns usuarios informaron que despois de engadir un formato de ficheiro á lista de extensións permitidas, atoparon algún erro. O texto do erro é semellante ó seguinte:

The file is corrupt or has an incorrect extension. Please check the file and upload again.

Solucións posíbeis:

Pon o valor de $wgMimeDetectorCommand, p.ex. correndo en Unix ou Linux, isto sería

  • $wgMimeDetectorCommand = "file --brief --mime";
  • Compile/install the fileinfo PHP extension
    • Fedora - yum install php-pecl-Fileinfo
Ver tamén: Manual:Mime type detectionManual:Mime type detection

O usuario inicial non foi creado polo instalador ou non é un administrador[edit]

Ás veces, o instalador falla ó crear o usuario por defecto, ou a táboa de usuario perdeuse por algunha razón. Hai un par de opcións para solucionar isto:

maintenance/createAndPromote.php[edit]

Se o teu MediaWiki é máis vello que 1.16, asegúrate de que AdminSettings.php está montado (mira AdminSettings.sample) Executa maintenance/createAndPromote.php --username <new user name> --Contrasinal <password for that user> na consola. Engade --bureaucrat na liña de comandos, se queres que o usuario sexa asemade un burócrata e un administrador.

Isto creará un usuario novo e promoverao a administrador. Para axuda, corre o script co parámetro --help.

Alterar a base de datos[edit]

Rexistrar unha conta nova que usando o método regular (Special:UserLogin). Verifica o ID de usuario en Special:Preferences. Executa a seguinte instrución SQL na base de datos:

    • INSERT INTO user_groups ( ug_user, ug_group ) VALUES ( <id>, 'bureaucrat' ), ( <id>, 'sysop' );
<id> enriba tería que ser substituído coa identidade de usuario apropiada que podes ver na páxina de preferencias do usuario.
Nota: se $wgDBprefix é definido en LocalSettings.php, prepend o seu valor ao nome de mesa. Por exemplo, se $wgDBprefix é "XYZ", entón o nome de mesa a uso é gruposde usuario_do XYZ

Temporalmente deixado todo o mundo atribúe dereitos de promover o voso usuario inicial[edit]

Warning Warning: Non terías que deixar outsiders acceder o voso wiki mentres fas isto, se utilizas este método. Este método pode deixar o voso wiki temporalmente vulnerábel de atacar mentres ti o procedemento.

Este método esencialmente implica deixar todos os usuarios temporalmente modifican permisos de usuario para promover un usuario Rexistrar unha conta nova que usando o método regular (Special:UserLogin). Ser entrado no sistema utilizando que conta. Engadir as liñas seguintes ao fondo de LocalSettings.php

    • $wgAddGroups['user'] = true;

Vai a especial:userrights e engadir o usuario ti só creado ao Administrador e Bureaucrat grupos. Tirar o $wgAddGroups['user'] = true; Liña desde o voso LocalSettings.php . Este paso é moi importante, cando até que tíralo calquera pode alterar permisos, o cal é malo.

Como mudo default preferencias de usuario?[edit]

MediaWiki version: 1.4

O MediaWiki default preferencias de usuario son no ficheiro de lingua, p.ex. Lingua/de linguas.php Se estás utilizando inglés. Non edita aquel ficheiro, só utilizalo para referencia, gosta fas con DefaultSettings.php.

Say if you want to change the default number of search results on a page. Language.php says:

 /* private */ $wgDefaultUserOptionsEn = array(
        ...
        'searchlimit'  => 20,
        ...
 )

Para mudalo a 50, instalado isto o voso LocalSettings.php:

 $wgDefaultUserOptions = array( 'searchlimit' => 50 );

Nota que estás pondo $wgDefaultUserOptions, o cal contén o sitio overrides, non $wgDefaultUserOptionsEn, o cal contén o software defaults. Calquera colocacións en $wgDefaultUserOptions override aqueles #chegar o ficheiro de lingua.

Para mudar o default namespaces para ser buscado, en calquera versión de MediaWiki, conxunto $wgNamespacesToBeSearchedDefault en LocalSettings.php A unha variedade mapping namespace índices a boolean valores. Por exemplo, para buscar o principal namespace e a categoría namespace, uso:

$wgNamespacesToBeSearchedDefault = array(
    NS_MAIN => true,
    NS_CATEGORY => true,
);

Nalgúns casos, despois de que mudas un default preferencia de usuario, tamén podes querer mudar as preferencias de usuario de todas contas de usuario existentes.

Se tan, uso o userOptions.php Guión no directorio de Mantemento. Uso o "--opción" seca para a primeira carreira, avaliar o impacto e ir desde alí. (--Seco non escribe a base de datos)

php userOptions.php --dry --nowarn searchlimit --old 20 --new 50

Also, always backup your database before making these kinds of changes (you do not need to if you are just using --dry).

Is it possible to move my wiki to a different machine?[edit]

Sí Tería que ser. En esencia, serás facer unha copia de seguridade a vosa instalación vella e entón "restaurándoo" á máquina nova. Finalmente, terás que facer modificacións adicionais para actualizar o wiki configuración de modo que todo sinala á localización nova.

Como movo a miña wiki a un diferente server?[edit]

Seguir as instrucións en Manual:Movendo un wiki.

Mudando a interface[edit]

Como mudo o logo?[edit]

The logo that appears in the top left of each page is determined by the $wgLogo configuration line in the LocalSettings.php file.

There are two ways to change the logo:

  1. Upload a picture to your wiki using the normal file uploading interface. Isto deixa o logo para ser substituído facilmente, así que podes querer protexer a páxina se utilizas este método.
    Entón engadir o $wgLogo liña a LocalSettings.php, por exemplo:
    $wgLogo = "{$wgUploadPath}/6/62/mylogo.png";
    
  2. Upload Unha imaxe ao voso server por outro medio (como FTP).
    Engadir o $wgLogo liña a LocalSettings.php, por exemplo:
    $wgLogo = "{$wgScriptPath}/mylogo.jpg";
    
    (Neste exemplo, a imaxe é no mesmo cartafol como o LocalSettings.php Ficheiro.)

Se queres mudar o logo en páxinas específicas únicas, override #p-logo css fondo-propiedade de imaxe ou uso terceira extensión de partido como Extensión:LogoFunctions.

Caution! Caution: Do not simply overwrite the default logo installed with MediaWiki (/skins/common/images/wiki.png); this file will be overwritten when you upgrade.
A good size for a square logo is 135x135px or 150x150px, but the logo need not be square, especially if it contains text below an image. The maximum logo size in Vector is ~160x160px, while MonoBook's is ~155x155px. A logo that is too large will be cut off.


How do I edit the wiki's CSS?[edit]

You shouldn't edit the CSS files (such as common.less) directly, because it will make upgrading harder if you need to apply your customizations each time you upgrade the software. Instead you need to edit a wiki page called MediaWiki:Common.css if you want to apply your CSS changes for all skins, or a wiki page called MediaWiki:Vector.css if you want to apply the customizations only for the Vector skin.

The content of the MediaWiki:Common.css and MediaWiki:Vector.css pages always overrides the default CSS styles specified in the skin files.

How do I hide the left vertical navigation toolbar[edit]

In other words, how do you make the main content div take up 100% of the display, hiding the logo, toolbox, navigation and search engine?

To hide it permanently, copy and paste the following into the MediaWiki:Common.css page:

#column-content { margin: 0 0 .6em 0; }
#content { margin: 2.8em 0 0 0; }
#p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search { display:none; }
#p-cactions { left: .1em; }

To instead hide the toolbar when the user presses F11, enter this in your wiki's MediaWiki:Common.js:

document.onkeydown = function( e ) {
	if( e == null ) e = event
	if( testKey( e, 122 ) ) { //F11
		appendCSS('#column-content {margin: 0 0 .6em 0;} #content {margin: 2.8em 0 0 0;} #p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search {display:none;} #p-cactions {left: .1em;} #footer {display:none;}');
		return false;
	}
}

function testKey( e, intKeyCode ) {
	if( window.createPopup )
		return e.keyCode == intKeyCode
	else
		return e.which == intKeyCode
}

How do I hide the categories at the bottom of each page?[edit]

You can hide display of the categories on each page by modifying your MediaWiki:Common.css and adding:

.catlinks { display: none; }

Can I customize the logo in the top left corner? If so, how?[edit]

The logo is a portlet block without a pBody section. It is identified by the p-logo id. The background image is specified by the $wgLogo variable, which is defined in DefaultSettings.php. This location is relative to the web server root and not the system root. Redefine this in LocalSettings.php to change the image. If set wrong there will be no image on the page; check your web server error log and adjust accordingly. However the size of the p-logo will need to be big enough for the logo if it is not to be clipped. This is set in the stylesheet (main.css in Monobook), under the p-logo style, the default setting is:

#p-logo {
	z-index: 3;
	position: absolute; /*needed to use z-index */
	top: 0;
	left: 0;
	height: 155px;
	width: 12em;
	overflow: visible;
}

Note, if you are using a different sized logo, and want to change the CSS, please do not modify any of the core MediaWiki stylesheets. Instead add to the on-wiki css page (MediaWiki:Monobook.css for monobook, MediaWiki:Vector.css for vector. MediaWiki:Common.css will also work for all skins)

[edit]

Note that a tag is on top of the logo so if you are trying to reduce the size of the logo's portlet you will also need to change the #p-logo a and #p-logo a:hover rules. The default setting for these is:

#p-logo a,
#p-logo a:hover {
	display: block;
	height: 200px;
	width: 12.2em;
	background-repeat: no-repeat;
	background-position: 35% 50% !important;
	text-decoration: none;
}

How do I customize the link-URL of the site-logo in the top left corner of all pages that activates when the site-logo is clicked upon?[edit]

By default, clicking the site-logo takes you to the main site-page. If you want to change which internal site-page is the "main" site-page, edit MediaWiki:Mainpage.

To make the link of the site-logo link externally to any other arbitrary URL, you can add a hook to your LocalSettings.php to override the mainpage href which is used by the logo.

/* Change the main page url used in things like the logo to an absolute url */
$wgHooks['SkinTemplateOutputPageBeforeExec'][] = 'lfChangeMainPageURL';
function lfChangeMainPageURL( $sk, &$tpl ) {
	$tpl->data['nav_urls']['mainpage']['href'] = "http://www.your-desired-url.com/"; // Point the main page url to an absolute url
	return true;
}

/* Change the main page url used in things like the logo to a url of another page on the wiki */
$wgHooks['SkinTemplateOutputPageBeforeExec'][] = 'lfChangeMainPageURL';
function lfChangeMainPageURL( $sk, &$tpl ) {
	$tpl->data['nav_urls']['mainpage']['href'] = Title::newFromText('ThePage')->getLocalURL(); // Point the main page url to a wiki page's url
	return true;
}

How do I change the icon in the browser's address line (favicon)?[edit]

  • Simply upload your favicon.ico to the root of your domain/subdomain, make sure file name is in lower case and its name is favicon.ico
  • Alternatively edit the $wgFavicon setting in LocalSettings.php and add $wgFavicon = "$wgScriptPath/path/to/your/favicon.ico";

See Manual:$wgFavicon for more details.

Tip: The favicon image should be either 16 x 16 pixels or 32 x 32 pixels.

Rewrite Rule[edit]

If you are using a rewrite rule in .htaccess to remove "index.php" from the URL, you will also need to add an exception for .ico files. Simply add the following rule to your .htaccess:

RewriteRule .*\.ico$ - [L]

This rule must appear before the index.php rule.

Case sensitivity[edit]

When uploading the favicon file, be sure the filename is in lowercase. (That is, "favicon.ico", not "Favicon.ico".) A lot of servers (e.g., those on UNIX-like operating systems) will not be able to find the file unless its name is in lowercase.

How do I customize the navigation bar?[edit]

The contents of the navigation bar which appears to the left of each page using the Vector or the Monobook skin are determined by the MediaWiki:Sidebar page there on your wiki. For information on customising these, please see Manual:Interface/Sidebar.

How do I put a text message (sitenotice) on every page?[edit]

Put a text in the MediaWiki:Sitenotice page. It will be displayed on top of every article page.

You can also add text to MediaWiki:Anonnotice to create a message that only displays for logged-out users. It is often a good idea to transclude the site notice on the anon notice to make sure that logged-out users still get the information on the site notice.

How do I change which page is the main page?[edit]

By default, MediaWiki looks for a page with the title Main Page and serves this as the default page. This can be changed by altering the contents of MediaWiki:Mainpage to point to a different title. If this does not change the 'Main Page' link included on the sidebar at install time, edit MediaWiki:Sidebar.

How do I change the Main Page title?[edit]

Simply click on the "Move" tab, and move the page to the desired page title.

Usually you also want to change which page is the configured as "main page".

How do I hide the main page title?[edit]

MediaWiki does not have a built-in option to hide the main page title (see task T8129), but you can use CSS to hide the title. Alternatively, you can use the NoTitle extension.

Add the following to MediaWiki:Common.css on your wiki:

body.page-Main_Page.action-view h1.firstHeading, body.page-Main_Page.action-submit h1.firstHeading { display: none; }

If your main page uses a localized name or you have renamed the main page you need to change the page-Main_Page part. You can find a correct parameter by viewing HTML source of the main page and searching for the body tag.

For example, if your language is Lojban, the body tag looks like this:


<body class="mediawiki ltr sitedir-ltr ns-4 ns-subject page-uikipedi_as_ralju skin-vector action-view">

Therefore you should put this line in your MediaWiki:Common.css instead:

body.page-uikipedi_as_ralju.action-view h1.firstHeading, body.page-uikipedi_as_ralju.action-submit h1.firstHeading { display: none; }

If you would like to hide the title of a "Main Page" in a specific namespace like "Help:Main_Page" add the following to MediaWiki:Common.css on your wiki:

body.page-Help_Main_Page.action-view h1.firstHeading, body.page-Help_Main_Page.action-submit h1.firstHeading { display: none; }

Note the difference: body.page-Help_Main_Page in comparison to body.page-Help:Main_Page. The latter will not work.

If this doesn't work, you may be using a skin that doesn't support this, or you moved your main page without updating MediaWiki:Mainpage, or you have a really old MediaWiki version.

If the skin uses a different element for the title than a h1 element with class firstHeading, you'll need to find the appropriate CSS selector to apply for that skin.

How can I hide the table of contents?[edit]

The table of contents (TOC) is automatically shown once there are four or more headings in the article. There are multiple ways to hide it.

For one page
Place the magic word __NOTOC__ in the page's wikitext.
For all pages
Install Extension:NoTOC
or
Add the following rule to MediaWiki:Common.css:
.toc, #toc { display: none; }
Per user
Users can add the same CSS rule to their common.css personal stylesheet.
MediaWiki version: 1.22
Gerrit change 99430
There was a user preference to hide the table of contents, it was removed in MediaWiki 1.23 (phab:T54813).

How do I change the interface text?[edit]

Interface text is altered using the MediaWiki namespace. For each deviation from the default in the site language there is a page MediaWiki:Englishmessagename, and for each deviation from the default in each other language a page MediaWiki:Englishmessagename/languagecode. (Since release 1.9 there are no pages for messages equal to the default.). On creation of a page the edit box autofills with the default. When creating a page to override the default it is useful to first save the default version, to allow diffs with it. See also Help:System messageHelp:System message.

How do I change the interface language?[edit]

To change the default interface language, alter the value of $wgLanguageCode in LocalSettings.php, for example

$wgLanguageCode = "fr";

You may also need to bypass your browser's cache to see the changes.

The new default interface language will be applied to all users who haven't ever customised it.

If you want to provide users the possibility to create and choose pages and interface elements in languages other than the default one of the wiki, you need the Translate extension, which can make your wiki multilingual.

In old versions, the new default will not affect existing users, so if you're logged in, you will need to change your language settings in your preferences.

If you want to change the language settings for all existing users, use the userOptions.php maintenance script. For instance, to have all users with English set use French instead, run:

php userOptions.php language --old en --new fr

How do I remove the article/edit etc tabs?[edit]

For a little more control see: User:Subfader/Hide_page_tabs

Edit MediaWiki:Common.css on your wiki, and add this:

li#ca-edit { display: none; }

See the page source for the various #ca-* ids used in the content tabs.

Note: this will only work for Monobook and derived skins such as Modern and Vector (the default skin), and doesn't actually stop people from editing. To do that, see Manual:User rights.

How do I add/remove tabs throughout my wiki?[edit]

Use Extension:DynamicTabs on older MediaWiki installations or write your own extension (See: Manual:Hooks/SkinTemplateNavigation):

For example, to remove the talk tab and then add a tab that always goes to the main page you would save this code in extensions/AR-Tabs.php:


MediaWiki version: 1.21
<?php
if( !defined( 'MEDIAWIKI' ) ){
	die( "This is not a valid access point.\n" );
}

$wgHooks['SkinTemplateNavigation'][] = 'replaceTabs';
function replaceTabs( &$skin, &$links) {  
	// Remove the talk action
	unset( $links['namespaces']['talk'] );
	$maintitle = Title::newFromText( wfMessage( 'mainpage' )->inContentLanguage()->text() );
	// Add an additional link
	$links['namespaces']['main'] = array(
		'class' => false, // false or 'selected', defines whether the tab should be highlighted
		'text' => wfMessage( 'sitetitle' )->text(), // what the tab says
		'href' => $maintitle->getFullURL(), // where it links to
		'context' => 'main',
	);
	return true;
}

and then add

require_once("extensions/AR-Tabs.php");

to the bottom of LocalSettings.php

How do I remove a tab on only one page?[edit]

MediaWiki version: 1.9

For example, to remove the Discussion (talk) page tab from the Main Page, on the MediaWiki:Common.css page add:

body.page-Main_Page li#ca-talk { display: none !important; }

To modify MediaWiki:Common.css you must have administrative privileges.

See also: Manual:Hide page tabsManual:Hide page tabs

How do I remove a tab on all pages[edit]

MediaWiki version: 1.9

For example, to remove the Discussion (talk) page tab on all wikipages, on the MediaWiki:Common.css page add:

#ca-talk { display:none!important; }

Other tabs to remove are #ca-history, #ca-viewsource, #ca-view (Read tab), #ca-nstab-main (Page tab).

Other drop down menu items you can remove are #ca-watch, #ca-move, #ca-delete.

To modify MediaWiki:Common.css you must have administrative privileges.

How do I hide the section edit links for users who are not logged in?[edit]

You can change the value of the $wgDefaultUserOptions configuration option.

Edit LocalSettings.php and add the line:

$wgDefaultUserOptions ['editsection'] = false;
Also see How do I stop anonymous users from editing any page?

How do I remove the "Talk for this IP" link at the top right (e.g. when $wgDisableAnonTalk is true)?[edit]

One option is to hide the link using the following CSS in the wiki page MediaWiki:Common.css in your wiki:

#p-personal #pt-anonuserpage {
    display: none;
}

Another option is, inside your LocalSettings.php file, to use the PersonalUrls hook to remove the link to the talk page of anonymous users:

$wgHooks['PersonalUrls'][] = 'lfRemoveAnonUserpageLink';
function lfRemoveAnonUserpageLink( &$personal_urls, $title ) {
	unset( $personal_urls['anonuserpage'] );
	return true;
}

How do I remove the "Create an Account or Login" link at the top right of the screen?[edit]

To remove the login / create account links from the personal_urls you can use this code in your LocalSettings.php to hook in and remove them:

$wgHooks['PersonalUrls'][] = 'lfRemoveLoginLink';
function lfRemoveLoginLink( &$personal_urls, $title ) {
	unset( $personal_urls['login'] );
	unset( $personal_urls['anonlogin'] );
	unset( $personal_urls['createaccount'] );
	return true;
}

How can I suppress actions and special pages?[edit]

NOTE: MediaWiki is not designed for this kind of usage! It should be noted that the following 'answer' is a hack that only 'works' with the Apache webserver. Note also that this system is not foolproof, it's just one step further than hiding the links (see above).

Suppressing actions and special pages can be useful when you want to create the illusion of a static website via a particular URL or VirtualHost, but also have an 'internal' view that is a true wiki. i.e. if you have an inward facing 'view' of your wiki that users can edit, and an outward facing 'view' that should appear like a static website (no history, no discussion, etc., etc.).

After hiding all the appropriate links (see above), if you are using the Apache web server, you can disable actions and special pages using the following rewrite rules:

# Lock down the site (disable MediaWiki commands)

RewriteEngine On

#RewriteLog /tmp/rewrite.log

#RewriteLogLevel 9

## See http://www.mediawiki.org/wiki/Manual:Parameters_to_index.php#Actions

RewriteCond %{QUERY_STRING} (.*action=.*)
RewriteRule .* http://www.my.domain.com?

RewriteCond %{REQUEST_URI} !^/index.php/Special:Search
RewriteCond %{REQUEST_URI}  ^(.*Special:.*)
RewriteRule .* http://www.my.domain.com?

## Catch a trick...
RewriteCond %{QUERY_STRING} ^(.*Special:.*)
RewriteRule .* http://www.my.domain.com?

Above, a request for 'http://www.my.domain.com/wiki/Page_name?action=edit', for example, will be simply rewritten to 'http://www.my.domain.com'. Similarly any page in the Special namespace (with the exception of Special:Search) will be rewritten to 'http://www.my.domain.com'. Remember, this is only a hack, and isn't intended as a solution for a secure CMS.

Note that you will need to adjust the above rules to match your specific URL naming schema.

Other issues to consider when trying to lock down a site like this is the API and POST requests for the wiki content (rather than GET).

How do I edit error messages?[edit]

Special:Allmessages contains a complete list of messages (error or otherwise), that can be edited.

How do I change the footer?[edit]

See Manual:Footer and Manual:Configuration settings#Copyright

How can I edit / remove the Powered by MediaWiki image (and possible other images) from the footer?[edit]

You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css:

#footer-poweredbyico { display: none; }

If you want to remove it completely in 1.17 and newer you can use $wgFooterIcons to remove it using this in your LocalSettings.php:

unset( $wgFooterIcons['poweredby'] );


MediaWiki version: 1.16

In 1.16 and below you will have to use a hook to remove it:

$wgHooks['SkinTemplateOutputPageBeforeExec'][] = 'lfRemovePoweredBy';
function lfRemovePoweredBy( $sk, &$tpl ) {
	unset( $this->data['poweredbyico'] );
	return true;
}

Note that this will also remove other powered-by icons, e.g. also the one coming from BlueSpice.

If you wish to change the icon images, urls, alt text, or add new icons please see $wgFooterIcons' documentation.

How do I add a reply link to default signature tildes (~~~~) template?[edit]

You can customize signatures in MediaWiki:Signature / MediaWiki:Signature-anon.

For example, changing the entries to [[{{ns:user}}:$1|$2]] ([[{{ns:user_talk}}:$1|talk]]) will put a link to users' talk pages and [[{{ns:user}}:$1|$2]] ([{{fullurl:{{ns:user_talk}}:$1|action=edit&section=new}} Reply]) would give a more direct link.

Users can change their signature in their preferences.

How can I change what the <title> of each page is? Where do I make changes?[edit]

Most of the text that you want to change can be found in the namespace of MediaWiki.

In order to change titles, texts, announcements, etc., go to Special:AllMessages, where you will see the text associated with the pages you wish to change. You need to log in as an administrator to edit the protected entries in the MediaWiki namespace.

If you want to change the title in your browser, you need to edit MediaWiki:Pagetitle. Go there and edit it just like you would any other page in your wiki.

In recent versions of MediaWiki, MediaWiki:Pagetitle is $1 - {{SITENAME}} by default. If {{SITENAME}} is producing the wrong text for you, you need to set $wgSitename in your LocalSettings.php.

If $wgSitename is correct in LocalSettings.php but {{SITENAME}} is still wrong, it may be that you're using a user-contributed language file which incorrectly sets $wgSitename to a transliteration of "Wikipedia". Edit the language file to correct this. For example, the Hebrew language file is at languages/LanguageHe.php in your wiki directory.

Don't forget to clear your browser cache after you change your settings.

Does MediaWiki automatically capitalize the first letter of $wgSitename?[edit]

Yes. This can be changed using the $wgCapitalLinksManual:$wgCapitalLinks configuration setting.

How do I make external links open in a new window?[edit]

See Manual:$wgExternalLinkTarget

How can I suppress MediaWiki from formatting URLs, tags, etc?[edit]

Put "<nowiki>" tags around the URL or tag.

Example:

svn co <nowiki>http://svn.example.com/myproject/</nowiki>

Produces:
svn co http://svn.example.com/myproject/

How can I force users to preview before they save?[edit]

See: Manual:Force preview and Extension:ForcePreview

How do I add more buttons on the edit page?[edit]

See: Manual:Custom edit buttons

How can I get more special characters or tags clickable on the edit page?[edit]

For adding more selectable special characters, etc., below the edit field, see Extension:CharInsert.

How can I use a different skin (e.g. Wikipedia's old Monobook skin) on my wiki?[edit]

MediaWiki version: 1.16

While the Vector skin is the default skin for all installations made with MediaWiki 1.17 and newer, the Monobook skin has been the default before. See Manual:$wgDefaultSkin for more information on configuring your default skin.

How do I disable external links from showing in the printable version of a page?[edit]

Edit the page MediaWiki:Print.css on your wiki and add the following code there:

#content a.external.text:after,
#content a.external.autonumber:after {
	content: none;
}

This will override the styles defined in the CSS files coming with the MediaWiki source code. For more information, see Manual:CSS.

If instead you want to have the external links underlined in the printable version, then also add the following code:

#content a.external {
    text-decoration: underline !important;
}

How do I change the text of the article (page name) tab of my wiki's main page?[edit]

To change the text of the tab, as one example used in Wikipedia, you first open the page "MediaWiki:Mainpage-nstab".

After you've done that, click Edit and type in the edit box the text you want to be seen later on the main page - that's it. Don't forget to save the page as well.

Basic usage[edit]

How do I edit a page?[edit]

To edit a page, simply click the edit link that appears on each page. Using the default Vector skin, this is in the form of a tab at the top of the page. A form will appear, containing the existing markup. When you have finished making modifications, click the Save button to commit your changes.

How do I create a new page?[edit]

There are several ways to create a new page:

  • Create a link to the page on another page, then click on the red link which appears
  • Browse to the intended location of the page, e.g. http://www.example.com/index.php?title=New_page and click on the "Edit", "Create" or "Create source" link.

On some wikis, a failed search for a page will contain a link which allows you to edit that page.

How do I delete an old version of a page?[edit]

Old versions of page data are retained in the database and can be accessed via the page history features. This is useful for reviewing changes and correcting or reverting undesirable ones, but in some cases, administrators might want to make this information unavailable, for legal reasons, or to reduce the size of the database.

  • Administrators can delete an old revision of a page by deleting the page, and then selectively undeleting revisions to be kept
  • The Oversight extension (also known as HideRevision) can be used to move harmful revisions out of page histories on older versions of MediaWiki (<1.16).
  • For newer MediaWikis (1.14+), you can enable the core RevisionDelete feature that allows privileged users to remove single revisions from page histories.
  • The maintenance/deleteOldRevisions.php maintenance script can mass-delete all old revisions of pages and their associated text records.
See also: Manual:Removing embarrassmentManual:Removing embarrassment

How do I use oversight/delete revisions in the page history?[edit]

See: RevisionDeleteRevisionDelete

You can also delete a page, and then restore only the revisions you want.

Are there any editing tutorials available?[edit]

There are several editing tutorials available, mostly on Wikimedia sister projects, such as Wikipedia. There are also markup references, etc. available on Meta.

How do I view the printable form of a page?[edit]

MediaWiki includes stylesheets which automatically style a page appropriately when it is printed; using the print or print preview function within your browser ought to render the page in a printable form.

You can also view this printable form using the printable version link in the sidebar under Toolbox or Print/export if using the Collection extension.

How do I use templates?[edit]

See Help:Templates

Can I use media (images, video, audio, etc.) from Wikimedia Commons in my installed version of MediaWiki?[edit]

Yes, this is encouraged through the use of Manual:$wgUseInstantCommons.

See also: InstantCommonsInstantCommons

How do I use a template as a signature?[edit]

When you look at your preferences, you see a check box for "raw signature." But the field will only take a certain number of characters. What if you want more?

You will need to create two pages, possibly in your userspace.

  1. Create the first page (FIRST PAGE)
  2. Go to your preferences, check "raw signature" and put {{FIRST PAGE}} in the signature. Gardar
  3. Create a second page (SECOND PAGE) (possibly a sub-page of the first)
  4. Go back to the first page (FIRST PAGE) and do {{SECOND PAGE}}
  5. Go to the second page (SECOND PAGE) and place the code you wish to have for your signature.

If you don't have this structure, you will still be inserting all your signature code into the raw code wherever your signature is used, because the software will insert "SUBST" in your preferences. You may not mind this, in which case you only need one page. If you want the raw code to only display {{FIRST PAGE}}, which looks a lot cleaner, then you need to use the two-page structure.

How do I add the sandbox functionality to my installation of the wiki?[edit]

In wiki terms, a sandbox is simply a "play pen"; a page which users can mess about in. This is an ordinary page created in the normal manner, and can be located wherever you like. There is no special sandbox functionality built into MediaWiki.

Users often inquire about the Wikipedia sandboxes, which seem to be self-emptying. This is not quite correct; there are a number of volunteers who run bots to clean these up and return them to a certain state at regular time intervals.

How do I add a "Sandbox" link to personal tools (top right)?[edit]

You need to add the Gadget extension and add the Sandbox gadget. You will probably also want to make it a default gadget.

How do I make my wiki serve all languages?[edit]

To make your wiki multilingual and a tool for translation, allowing translation of pages and of the custom interface (like the sidebar), use the Translate extension; there's extensive documentation.

Wiki Importing[edit]

Importing from MediaWiki XML dumps[edit]

See Manual:Importing XML dumps

Importing from other types of wiki software[edit]

Note: The following is directly copied from old meta FAQ. It might need to be corrected.

There is some documentation about importing in the UPGRADE file distributed with MediaWiki.

To follow on from those, this is how at least one individual imported pages from usemod to MediaWiki:

Because MediaWiki does not automatically link to CamelCase style links, you will need to add brackets [[ ]] to all your links. You can do this with the following:

First, obtain ImportStage1.txt (or whatever you want to call it) from the importUseModWiki.php script ( use > to pipe the output to a file )

Second, do

sed '/Importing/!s/\ [A-Z]\w*[a-z]\w*[A-Z]\w*[a-zA-Z]/\ \[\[&\]\] /g'
    ImportStage1.txt > ImportStage2.txt

This should create proper links in place of your CamelCase links.

This doesn't work so well for SubPage links - someone care to fix?

Then,

sed 's/upload\:\w*\.\w*/http\:\/\/aberwiki\.org\/uploads\/& /g'
    ImportStage2.txt > ImportStage3.txt

This fixes your upload links. Change the replace text so it fills in your url such as http://www.yourwiki.org/uploads/filename

You are now ready to import ImportStage3.txt into your database with a command such as

mysql -u<mysqluser> -p<yourpass> <db name> < ImportStage3.txt

Note: If your importUseModWiki.php outputs an XML file instead of SQL statements, this probably means you have a rather new version of MediaWiki. In such a case, you can import the XML file -- see Importing a Wikipedia database dump into MediaWiki, towards the bottom of the page ('Import XML'). Don't forget to rebuild all the tables -- that page also explains how to do that.

Importing from other types of files[edit]

There are a variety of tools available to help convert content from HTML (and other formats) to MediaWiki markup.

MediaWiki auto importing script[edit]

Taken from wiki_import - MediaWiki auto import script:

Description[edit]

The script is designed to import a whole folder of files into MediaWiki, with the folder directory tree mapped as wiki category hierarchy.

Features[edit]

  • economic, build wiki site from existing knowledge base collection without "double-entry"
  • persistent, map folder directory tree as wiki category hierarchy
  • sophisticated, import/handle all well-known file types automatically
  • complete, cover every applicable scenario, even the case when you need to control access to individual wiki pages
  • versatile, highly customizable

Quick Help[edit]

wiki_import.sh $ $Revision: 1.1 $

mediawiki automatic file import script

Usage: wiki_import.sh [OPTIONS]...

The script is designed to import a whole folder of files into mediawiki, with the folder directory tree mapped as wiki category hierarchy.

The specification of the file-to-import is passed from standard input.

Options:

 -s, --sect=n     the root category section of the wiki of the imported article (mandatory)
 -1, --header     include standard header (category hierarchy path & notice)
 -l, --link       link to actual file on the web site
 -f, --footer     include standard footer (article category)
 -R, --res[=p]    add restricted tag in the footer as
                    '{{<Res Param|Root Category> Restricted}}' (default=`$_opt_sect')

Configuration Options:

 -p, --php=fn     mediawiki import php script specification
 -r, --root=n     the root category name for the whole wiki site
 -m, --max=n      max_allowed_packet for mysqld to import
 -u, --user=n     wiki user used for the import
 -a, --arch=p     the root url that linked-to archive files based on

Examples:

 echo ./path/to/file.ext | wiki_import.sh -1 -l -f -s 'Customer Support' -R 

For the rest of details, check out wiki_import.

Templates imported from other wikis (such as Wikipedia) don't work for me[edit]

You probably need to install some extensions used on the source wiki, such as ParserFunctions or sometimes Cite. Also, make sure that you copied all site CSS and JavaScript required by the template.

Customising further[edit]

I want to have multiple wikis, but only require registration once[edit]

  • If you're starting from scratch or you're switching from one wiki to multiple, you can use $wgSharedDB and $wgSharedTables to have all wikis share the user table of the "main" wiki. You can share other tables as well, as long as they don't contain any data dependent on non-shared tables or data specific to one wiki. See Manual:Shared database for examples and more information.
  • If your wikis are already established and you want to switch to a single sign-on, you can use the CentralAuth extension. It has a few more features than a shared user table, but it's more difficult to configure and it's tailored toward a Wikimedia-style setup. However, it is easier than attempting to completely merge multiple user tables into one.

How can I allow use of HTML tags?[edit]

See Manual:$wgRawHtml as well as Manual:$wgGroupPermissions and Manual:Preventing access.

Caution! Caution: This can be easily abused to attack users

See Extension:Secure HTML and Extension:HTMLets for ways to make this safer.

How do I fix problems or add features to MediaWiki?[edit]

The basic steps to improving MediaWiki (that is, becoming a MediaWiki developer) are:

  • Install Git
  • Download the Git "clone" of the MediaWiki source code
  • Get a server, a database, and PHP running on your computer (this can be annoying, so please ask for help if something isn't working)
  • Get MediaWiki running on your computer off that Git checkout (can be annoying as well, so, ditto)
  • Fix the problem or add the feature you were thinking of
  • Edit the source code of the relevant file(s) to fix the problem
  • Follow Gerrit/Tutorial

How do I run a bot?[edit]

See Manual:Bots

You might want to use the Pywikibot framework.

How do I change noindex nofollow[edit]

Set $wgNoFollowLinksManual:$wgNoFollowLinks = false; in LocalSettings.php

How do I create a small wiki farm?[edit]

See: Manual:Wiki family

How do I add meta tags?[edit]

The OutputPage class includes an addMeta method which can be used to add meta tags. The RequestContext can be used to get the relevant OutputPage object.

To add further Meta tags just add further lines as last lines of the function addMetaTags() like:

$out->addMeta ( 'description', 'This is a meta description.' );

Why...?[edit]

…is the Help namespace empty?[edit]

The Help namespace currently ships in a blank state. It's up to you how much or how little help you give to your site visitors and whether this relates to other aspects of your site. Obviously you can easily link your visitors to help resources elsewhere.

We don't currently have a clean, internationalised set of help pages under a free license. However, if you want to copy in some help information onto your site, about how to use a wiki (a MediaWiki powered wiki) you are free to copy the Help:Contents from this wiki. This set of pages have been deliberately created for this purpose, with wiki-neutral information, and no license restrictions. See Project:PD help. More help is available at the Meta-Wiki MediaWiki Handbook.

…are some of my images not showing up after an upgrade?[edit]

Several users have reported that, following an upgrade or a moving of their wiki, several images fail to be shown inline. The files exist, and the image description pages show a MIME type of unknowncode>/unknown and, in some cases, a warning about potentially dangerous files.

To fix this, run the maintenance/rebuildImages.php script from the command line. This will set MIME information for each file in the database.

…are all PNG files not being turned into thumbnails?[edit]

After upgrading to a more recent version of PHP, it is possible a different MimeMagic.php function is being used to detect file MIME types, particularly the built-in PHP function mime_content_type, which fails to detect PNG files. Search the web for mime_content_type png for information on fixing this bug at the PHP level, possibly by editing your magic.mime file.

See here for more info.

…is a search for a short keyword giving no hits?[edit]

By default, MediaWiki uses MyISAM's fulltext matching functionality to allow searching page content. The default settings for this mean that words of less than four characters won't be indexed, so will be ignored in searches with older versions of MediaWiki.

MediaWiki 1.13 and earlier are unable to work around this; you must either change MySQL/MariaDB's configuration to index shorter words, or upgrade to a more recent version of MediaWiki.

Note that some particular words may still not be indexed if they are in MySQL/MariaDB's default stopword list.

…can't I download MediaWiki 1.30?[edit]

MediaWiki 1.30 is in a development state at present, and has not been packaged into a general release. The code can be downloaded from Git if desired. Or, if you want the latest development version packaged as an archive, get it at mwSnapshots.

…doesn't this work? It works on Wikipedia![edit]

Wikipedia and other Wikimedia web sites use the current version of the code in development; at present, this is MediaWiki 1.31.0-wmf.8 (30a4750), pulled from the current development branch. Coupled with the use of several extensions, this means that functionality between these wikis and your particular setup may differ.

  • To obtain the current development code, read Download from Git
  • To check what version a Wikimedia wiki is running, as well as what extensions are installed, visit the Special:Version page for that wiki

…do I get a 403 Forbidden error after setting permissions on my Fedora system?[edit]

Fedora Core enables SELinux by default. Instructions for setting SELinux permissions for MediaWiki are available.

…do I get logged out constantly?[edit]

This is probably related to cookies or session data, for example a problem with PHP's session.save_path setting. See Log in problems for information.

If this is happening constantly to all users, it probably means that caching is misconfigured. Setting $wgSessionCacheType = CACHE_DB; can be used to determine if caching is the cause of the problem. If that solves the problem, you should still investigate what is wrong with your caching configuration.

…doesn't my wiki work on Sourceforge?[edit]

See Manual:Installing MediaWiki on SourceForge.net.

…is it a good idea to keep user accounts?[edit]

At many times you just want to remove a user account out of the wiki either because it belonged to a spammer account or you just feel like it. The appropriate choice is to block the account or rename it if needed. Here is why:

Do I just remove his row from the User table?

Rob Church posted the following regarding this issue on the wikitech-l mailing list:

"If the user has made edits, then removing rows from the user table cause theoretical loss of referential integrity. Now, to be honest with you, I can't think of any conditions where this would cause an actual problem; "undefined behaviour" is the phrase we use.

What I'd suggest doing, to be on the safe side, is running a couple of quick updates against the database:

UPDATE revision SET rev_user = 0 WHERE rev_user = <current_user_id>
UPDATE archive SET ar_user = 0 WHERE ar_user = <current_user_id>

What this will do is cause MediaWiki to treat the revisions as having been made anonymously when generating things like page histories, which should eliminate any problems caused by these routines attempting to check user details from other tables.

If the user has caused log entries, i.e. rows in the logging table, or uploaded images, then the situation becomes trickier, as you'll have to start mopping up all the rows everywhere and it could become a bit of a mess, so if the user's done anything other than edit, I would strongly recommend just blocking them indefinitely.

If the username is offensive or undesirable, then you could consider renaming it using the RenameUser extension."

Another option is to give Admins the 'hideuser' right, and indefinitely block the user with the Hide username from edits and lists option selected.

Extension:UserMerge is also useful.

Anti-spam[edit]

Where do I get the spam blacklist from and how do I install it?[edit]

The spam blacklist extension can be found in Git, just like all other officially supported extensions. For installation and configuration instructions, consult the README file and extension page over here.

How do I use $wgSpamRegex to block more than one string?[edit]

$wgSpamRegex (see Manual) is a powerful filter for page content. Adding multiple items to the regex, however, can be awkward. Consider this snippet:

$wgSpamRegexLines[] = 'display\s*:\s*none';
$wgSpamRegexLines[] = 'overflow\s*:\s*auto';
[...]
$wgSpamRegex = '/(' . implode( '|', $wgSpamRegexLines ) . ')/i';

This example code allows convenient addition of additional items to the regex without fiddling about each time. It also demonstrates two popular filters, which block some of the most common spam attacks.

See also: Extension:SpamRegex

Are there additional ways to fight spam?[edit]

See Manual:Combating spam for an overview of anti-spam measures such as Captcha, content filtering and restricting edition.

Anti-vandalism[edit]

See Manual:Combating vandalism for hints and suggestions on how to deal with wiki vandalism.

Where now?[edit]

I've found a bug or have a feature request. Where do I post it?[edit]

Bugs and feature requests should be posted on Phabricator. See How to report a bug.

I'm getting a strange error. What now?[edit]

I tried that but it didn't work[edit]

I had a problem, I came to this page and it told me how to fix it. But it didn't work, the problem is still there!!!!

Nine times out of ten this is because you didn't clear your cache. The simple test for this is to request a page that hasn't been requested before. Select the part of the URL in the address bar that contains the page title (e.g. Main_Page). Twiddle your fingers on the keyboard for a while, hit enter. Check if the problem is on that page too.

MediaWiki uses both a server-side cache and a client-side cache, so clearing your browser cache is often not enough. See the relevant entry above for more details.

Here are some other things to check:

  • Were you editing the right file? Try inserting some garbage into the file you edited, does it break anything?
    • A great debugging tool in this case is to create a file called phpinfo.php, containing only <?php phpinfo() ?>. Upload it into your web directory and invoke it with your browser. Check the document root and the path to php.ini.
  • Were you editing the right part of the file? Did you create a duplicate entry in php.ini? Add new settings to the end of LocalSettings.php, not to the beginning.
  • If you created a .htaccess, are you sure AllowOverrides is on? Ask your hosting provider.
