What are the differences between MediaWiki, Wikimedia, Wikipedia and wiki?
This is a common question; please see Differences between Wikipedia, Wikimedia, MediaWiki, and wiki for a detailed answer.

I want to use a MediaWiki instance to (blank). Am I allowed to?
MediaWiki is free software: this means that you may use it for any purpose without legal hindrance. Furthermore, its licensing conditions apply solely to the software itself. This means that although many wikis license their content under a permissive license, you are not obliged to license the content submitted to your wiki in any particular way. Of course, as a project founded to support sites like Wikipedia, we encourage you to license the texts you write under a free license, but, in short, you are not required to.

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. Because MediaWiki is provided free of charge, there is no warranty, to the extent permitted by applicable law.

Où puis-je télécharger MediaWiki ?
La dernière version stable de MediaWiki peut être téléchargée à partir de http://sourceforge.net/project/showfiles.php?group_id=34373. Vous devrez choisir un site miroir pour le téléchargement. Les fichiers sont fournis dans une archive .tar.gz. MediaWiki peut aussi être obtenu directement à partir de notre référentiel Subversion (voir aussi fr:Subversion (logiciel)).Vous pouvez utiliser le logiciel wikimedia pour vos projets opensource

Comment puis-je installer MediaWiki ?
Installer MediaWiki prend entre 10 et 30 minutes (lorsqu'on utilise MySQL), et implique de télécharger/copier des fichiers, créer une base de données et un utilisateur, et exécuter le script d'installation pour configurer le logiciel. Des instructions complètes peuvent être trouvées dans le fichier INSTALL fourni dans la distribution par archive. Il y a aussi un guide d'installation sur Meta.

Comment puis-je installer MediaWiki en utilisant un package ?
Bien qu'il existe des packages (par exemple Debian, RPM, etc.) disponibles pour installer MediaWiki sous un système d'exploitation Linux/Unix. Ceux-ci ne sont pas officiellement supportés par l'équipe de développement de MediaWiki et nous ne pouvons pas fournir d'assistance pour les installer, configurer et utiliser. Les communautés individuelles qui maintiennent de tels packages fourniront normalement le support et la documentation.

Be warned that third-party distributions may be older versions, so pay close attention to compatibility information for directions and extensions.


 * See also: Software bundles.

Puis-je installer plus d'un wiki sur un serveur en utilisant MediaWiki ?
Il est possible d'installer plus d'un wiki sur un serveur tant que :

OU
 * Vous utilisez une base de données différente pour chaque wiki
 * Vous utilisez un préfixe de base de données différent pour chaque wiki.

Pour plus d'information sur ces options, voir $wgDBname et $wgDBprefix respectivement.

Pour plus d'informations sur la configuration d'une famille de wikis, voir Manual:Wiki family/fr.

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.

Does MediaWiki work with safe_mode enabled?
Yes, but only to a limited degree. See Safe mode for information.

Does MediaWiki require shell access?
Shell access (SSH) is not required for installing MediaWiki, but it is highly recommended. Without shell access, it may even be difficult for you to get a backup of your wiki, or to upgrade to a new version. Some maintenance tasks are not possible at all without shell access. Many major extensions work best with shell access.

How do I install extensions?
See Manual:Extensions for information about installing and writing extensions. See the Category:Extensions to find existing extensions.

How do I add extra namespaces?
See Creating a custom namespace.

Comment puis-je permettre le téléchargement ou téléversement ?
Les téléchargements de fichiers sont une fonctionnalité de MediaWiki souvent utilisée, mais est désactivée par défaut dans toutes les versions finales actuelles. Pour les autoriser, faites d'abord un répertoire pour télécharger ou téléverser (par défaut images) dans lequel le serveur web a l'autorisation d'écrire (CHMOD 777 ou permettre à l'utilisateur Apache d'écrire dans celui-ci, etc.) et ensuite configurez $wgEnableUploads à true dans votre LocalSettings.php. If you get a "failed to mkdir" error when you try to upload, it probably means that there's a permissions problem.

How do I enable embedded math formulas?
MediaWiki allows embedded math formulas. See Extension:Math for complete setup instructions.

How do I set the timezone for my MediaWiki?

 * See: Manual:Timezone

Comment purger le cache d'une page
Pour purger le cache d'une page, ajoutez &action=purge à la fin de l'url de la page.

Par exemple http://www.mediawiki.org/w/index.php?title=Main_Page&action=purge

Or  to the end of the page's short form URL:

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


 * See also: Manual:Purge, Manual:Parameters to index.php.

How do I completely disable caching?
Add in your LocalSettings.php file the following lines: $wgEnableParserCache = false; $wgCachePages = false;

Comment puis-je permettre le téléchargement d'autres formats de fichier ?
MediaWiki demande à ce que les formats de fichier téléchargeables soient spécifiés en utilisant la directive de configuration $wgFileExtensions. Usually this directive is situated in LocalSettings.php in the root of your MediaWiki installation.

Par exemple, pour permettre de télécharger des fichiers PDF, ajoutez la ligne suivante dans LocalSettings.php :

To extend uploading to more than one type of file, use the following syntax


 * See also: Manual:Configuring file uploads

"File is corrupt or has an invalid extension"
Quelques utilisateurs ont rapporté que, après avoir ajouté un format de fichier dans la liste des extensions autorisées, une erreur survenait. Le texte de l'erreur est similaire au suivant :


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

La solution ceci est de

à vérifier la valeur de $wgMimeDetectorCommand et de la corriger si nécessaire. Par exemple, sous Unix, configurez ceci comme : Sinon l'extension fileinfo doit être compilée dans PHP.
 * Fedora - yum install php-pecl-Fileinfo


 * See also: Manual:Mime type detection.code>

Initial user was not created by installer or it is not an administrator
Sometimes, the installer fails to create the default user, or the user table is lost for some reason. There are a couple of options for solving this:

maintenance/createAndPromote.php

 * If your MediaWiki is older than 1.16, make sure  is set up (see  )
 * Execute  from the shell. Append   to command line if you want that user to become a bureaucrat, in addition to becoming an administrator.

This will create a new user and promote them to an administrator. For help, run the script with the parameter.

Alter the database

 * Register a new account using the regular method (Special:UserLogin).
 * Check the user ID in Special:Preferences.
 * Execute the following SQL statement against the database:
 * above should be replaced with the appropriate user ID which you can see on the user's preference page.
 * Note: if  is defined in LocalSettings.php, prepend its value to the table name. For example, if   is "XYZ", then the table name to use is
 * Note: if  is defined in LocalSettings.php, prepend its value to the table name. For example, if   is "XYZ", then the table name to use is

Temporarily let everyone assign rights to promote your initial user
You should not let outsiders access your wiki while you do this, if you use this method. This method may leave your wiki temporarily vulnerable to attack while you do the procedure.

This method essentially involves letting all users temporarily modify user permissions in order to promote one user
 * Register a new account using the regular method (Special:UserLogin). Be logged in using that account.
 * Add the following lines to the bottom of LocalSettings.php
 * Go to special:userrights and add the user you just created to the Administrator and Bureaucrat groups.
 * Remove the  line from your LocalSettings.php . This step is very important, as until you remove it anyone can alter permissions, which is bad.
 * Remove the  line from your LocalSettings.php . This step is very important, as until you remove it anyone can alter permissions, which is bad.

How do I reset a user's MediaWiki password?

 * See Manual:Resetting passwords

How can I create interwiki links in my wiki?

 * See Manual:Interwiki

How do I make my base URLs shorter?
(i.e. /wiki/Article_Name as opposed to /w/index.php?title=Article_Name)
 * See Manual:Short URL

How do I organize pages into subdirectories like /wiki/subdir/PageName?

 * See Manual:$wgNamespacesWithSubpages, Help:Subpages

Is downloading and using all of MediaWiki.org free?
Yes, it is free in the sense of Free software. See Project:Copyrights for licensing issues regarding the written content of this site.

How do I administrate/manage user rights?
 See Manual:User rights and Manual:User rights for general information. See Manual:Preventing access for methods and strategies for restricting access.

Comment empêcher l'édition par les utilisateurs anonymes ?
Ces permissions sont contrôlées par l'option de configuration $wgGroupPermissions. Edit  and add the line:

If you use Extension:AbuseFilter, any admin can also disable IP editing temporarily as needed.


 * Pour plus d'informations sur la configuration de cette option, voir la page Preventing Access sur Meta (en anglais).

How do I stop anonymous users from reading any page?
See also Manual:$wgWhitelistRead. See Manual:Preventing access for more information.
 * Add this to the bottom of LocalSettings.php:

How do I restrict account creation?

How do I put MediaWiki into Read Only mode?

 * See Manual:$wgReadOnly

How do I change default user preferences?
The MediaWiki default user preferences are in the language file, i.e.  if you're using English. Don't edit that file, just use it for reference, like you do with DefaultSettings.php.

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

To change it to 50, put this in your LocalSettings.php: Note that you are setting $wgDefaultUserOptions, which contains the site overrides, not $wgDefaultUserOptionsEn, which contains the software defaults. Any settings in $wgDefaultUserOptions will override those set in the language file.

To change the default namespaces to be searched, in any version of MediaWiki, set $wgNamespacesToBeSearchedDefault in LocalSettings.php to an array mapping namespace indexes to boolean values. For example, to search the main namespace and the category namespace, use:

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

In some cases, after you change a default user preference, you may also want to change the user preferences of all existing user accounts.

If so, use the userOptions.php script in the Maintenance directory. Use the "--dry" option for the first run, assess the impact and go from there. (--dry does not write the database)

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 do use if you are just using --dry).

Is it possible to move my wiki to a different machine?
Yes. It should be. In essence, you will be backing up your old installation and then "restoring" it onto the new machine. Finally, you will have to make additional modifications to update the wiki configuration so that everything points to the new location.

How do I move my wiki to a different server?
Follow the instructions at Manual:Moving a wiki.

Comment puis-je changer le logo ?
Le logo du site visible en haut à gauche de chaque page est déterminé par le préfixe de configuration $wgLogo inclus dans le fichier LocalSettings.php.

There are two ways to change the logo:


 * 1) Vous pouvez télécharger un fichier sur votre wiki et utiliser son adresse (ce qui permettra de plus facilement modifier le logo ou le protéger)
 * Then add the $wgLogo line to LocalSettings.php, for example:
 * 1) ou utiliser une image téléchargée sur votre serveur par d'autres moyens.
 * Add the $wgLogo line to LocalSettings.php, for example:
 * (In this example, the image is in the same folder as the LocalSettings.php file.)
 * (In this example, the image is in the same folder as the LocalSettings.php file.)
 * (In this example, the image is in the same folder as the LocalSettings.php file.)

If you want to change the logo in only specific pages, override #p-logo css's background-image property or use third party extension like Extension:LogoFunctions.

How do I edit the wiki's CSS?
You shouldn't edit the CSS files (such as main.css) 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:Monobook.css if you want to apply the customizations only for Monobook skin.

The content of MediaWiki:Common.css and MediaWiki:Monobook.css pages always override the default CSS styles specified in main.css.

How do I hide the left vertical navigation toolbar
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:

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

How do I hide the categories at the bottom of each page?
You can hide display of the categories on each page by modifying your MediaWiki:Common.css and adding:

Can I customize the logo in the top left corner? If so, how?
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:

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)

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?
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.

Reducing the size of the logo
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:

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

 * 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

See Manual:$wgFavicon for more details.

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

Rewrite Rule
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
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.

Comment puis-je personnaliser la barre de navigation ?
Le contenu de la barre de navigation qui apparaît à gauche de chaque page (lorsqu'on utilise le skin par défaut Monobook) est déterminé par la page MediaWiki:Sidebar. Pour plus d'information sur cette personnalisation possible, vous pouvez aller voir Manual:Navigation bar.

How do I put a text message (sitenotice) on every page?
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,

Comment puis-je changer la page d'accueil ?
Par défaut, MediaWiki montre une page avec le titre Main Page et donne celle-ci comme page par défaut. Ceci peut être changé en modifiant MediaWiki:Mainpage pour pointer vers un autre titre. 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?
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?
MediaWiki does not have a built-in option to hide the main page title (see ), but you can use CSS to hide the title. Alternatively, you can use the NoTitle extension.

Add the following to on your wiki:

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

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

Therefore you should put this line in your instead: 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  element with class , you'll need to find the appropriate CSS selector to apply for that skin.

Comment puis-je cacher la table des matières ?
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.


 * Pour une page
 * Placez le mot magique   dans le texte de la page.


 * Pour toutes les pages
 * Install Extension:NoTOC
 * or
 * Add the following rule to MediaWiki:Common.css:


 * Par utilisateur
 * Les utilisateurs peuvent aussi choisir de ne pas afficher leur propre table des matières. Ceci est une préférence de l'utilisateur et peut être modifiée dans Special:Preferences.


 * There was a user preference to hide the table of contents, it was removed in MediaWiki 1.23 (T54813).

Comment puis-je changer le texte de l'interface ?
le texte de l'interface est configurable en utilisant l'espace de nom MediaWiki. Par défaut, ces messages sont remplis avec le texte de la langue sélectionnée pendant l'installation ou la mise à jour. (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. Pour modifier le contenu d'un message système, éditez la page correspondante dans l'espace de nom (namespace) MediaWiki.


 * Pour avoir une liste de tous les messages système, voir Special:Allmessages
 * Pour désactiver l'espace de nom MediaWiki, voir le paramètre de configuration $wgUseDatabaseMessages.
 * To remove the Privacy policy or Disclaimers links at the bottom of each page, set the content of pages MediaWiki:Privacy or MediaWiki:Disclaimers respectively to a single hyphen.

Comment puis-je changer la langue de l'interface ?
Changez la valeur de $wgLanguageCode dans le fichier LocalSettings.php.

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:

How do I remove the article/edit etc tabs?
For a little more control see: User:Subfader/Hide_page_tabs

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

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?
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 :

and then add to the bottom of LocalSettings.php

How do I remove a tab on only one page?
For example, to remove the Discussion (talk) page tab from the Main Page, on the MediaWiki:Common.css page add:

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


 * See also: Manual:Hide page tabs

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

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

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?
You can change the value of the configuration option.

Edit and add the line:

How can I suppress actions and special pages?

 * 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:


 * 1) Lock down the site (disable MediaWiki commands)

RewriteEngine On


 * 1) RewriteLog /tmp/rewrite.log


 * 1) RewriteLogLevel 9


 * 1) 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?

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

Above, a request for, for example, will be simply rewritten to. Similarly any page in the Special namespace (with the exception of Special:Search) will be rewritten to. 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?
Special:Allmessages contains a complete list of messages (error or otherwise), that can be edited.

How do I change the footer?

 * See Manual:Footer and Manual:Configuration settings

How can I edit / remove the Powered by MediaWiki image in the footer?
You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css:

The Vector skin equivalent is:

In MW 1.17 with Vector Skin:

In MW 1.18 with Vector Skin:

If you want to remove it completely in 1.17 you can use to remove it using this in your :

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

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

How do I add a reply link to default signature tildes ( ~ ) template?
You can customize at: MediaWiki:Signature / MediaWiki:Signature-anon

For example, changing the entries to  will put a link to users' talk pages and   would give a more direct link.

Users can change it their preferences.

How can I change what the of each page is? Where do I make changes?
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 - by default. If is producing the wrong text for you, you need to set $wgSitename in your LocalSettings.php.

If $wgSitename is correct in LocalSettings.php but 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  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?
Yes. This can be changed using the $wgCapitalLinks configuration setting.

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

 * See Opening external links in a new window

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

How can I use Wikipedia's default skin (Vector) on my wiki?
Vector was introduced in MediaWiki version 1.16, and was made the default skin in 1.17. See Manual:$wgDefaultSkin for more information on configuring your default skin.

Additional features of the Vector skin are made available using the Vector extensions, which you must download and install separately.

How do I disable external links from showing in the printable version of a page?
Edit the page MediaWiki:Print.css on your wiki and add the following code there:

This will override the styles defined in skins/common/commonPrint.css in 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:

How do I change the text of the article (page name) tab of my wiki's main page?
To change the text of the tab, as one example used in Wikipedia, you first open the page " ".

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.

Comment éditer une page ?
Pour éditer une page, cliquez simplement sur le lien modifier qui apparaît sur chaque page. Lorsqu'on utilise le skin par défaut MonoBook, celui-ci est dans la liste d'onglets en haut de la page. Un formulaire apparaît, contenant le wikitexte (code source de la page) existant pour la page donnée. Lorsque vous avez fini vos modifications, cliquez sur le bouton Sauvegarder pour enregistrer vos changements. Ceux-ci apparaissent directement.

Comment créer une nouvelle page ?
Il y a plusieurs façons de créer une nouvelle page :

On some wikis, a failed search for a page will contain a link which allows you to edit that page.
 * Cliquer sur un lien rouge existant ; ou s'il n'y en a pas, en créer un (par exemple en lançant une recherche sur le nom de la page).
 * Aller à l'adresse de la page, par exemple http://www.foowiki.org/index.php/New_page et cliquer sur le lien modifier.

How do I delete an old version of a page?
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 script can mass-delete all old revisions of pages and their associated text records.


 * See also: Manual:Removing embarrassment

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

 * See: RevisionDelete

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

Existe-t-il des tutoriaux à propos de l'édition ?

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  in the signature.  Save
 * 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
 * 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, 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?
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)?
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?
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.

Importing from MediaWiki XML dumps

 * See Manual:Importing XML dumps

Importing from other types of wiki software
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 -p < ImportStage3.txt

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


 * Developer and SysAdmin tools
 * HTML::WikiConverter::MediaWiki - a Perl module for converting from HTML to MediaWiki markup.
 * Wikificator - a Javascript MediaWiki extension that converts XHTML to MediaWiki markup.
 * The Edit.php, importImages.php and ImportTextFile.php maintenance scripts can be used to import text and images into MediaWiki.


 * End-user tools
 * HTML to Wiki Converter - an online HTML to MediaWiki markup conversion service. (Based on HTML::WikiConverter::MediaWiki)
 * wikEd - a text editor for MediaWiki that can import HTML (including Microsoft Word-generated HTML.)


 * Instructions
 * Brief notes on converting from Microsoft .chm help files to MediaWiki

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

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

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

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

How do I fix problems or add features to MediaWiki?
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, or if you don't have one in mind, look at one of the "annoying little bug"s
 * Edit the source code of the relevant file(s) to fix the problem
 * Follow Gerrit/Tutorial

How do I run a bot?

 * See Manual:Bots

You might want to use the Pywikibot framework.

How do I change noindex nofollow

How do I add meta tags?
The OutputPage class includes an addMeta methods 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.' );

Nous n'avons pas actuellement un ensemble propre et internationalisé de pages d'aide sous licence libre. 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.

Nous n'avons pas actuellement un ensemble propre et internationalisé de pages d'aide sous licence libre. Vous êtes libre d'ajouter vos propres pages, pourvu que vous acceptiez de les mettre dans le domaine public pour l'espace de nom Help (les autres pages du site qui ne sont pas dans l'espace de nom Help sont sous Licence de documentation libre GNU).

...certaines de mes images n'apparaissent pas après une mise à jour ?
Plusieurs utilisateurs ont rapporté que, après une mise à jour ou un déplacement de leur wiki, plusieurs images ne s'affichaient pas. Les fichiers existent, et la page de description de l'image montre un type MIME unknown / unknown (inconnu) et dans certains cas un avertissement concernant les fichiers potentiellement dangereux.

La solution à cela est d'exécuter le script de maintenance rebuildImages.php à partir de la ligne de commande. Cela configure les types MIME pour tous les fichiers de la base de données, et devrait rétablir les choses à la normale.

...tous les fichiers PNG ne sont pas affichés en vignette ?
Après le téléchargement d'une version plus récente de PHP, il est possible qu'une fonction MimeMagic.php soit utilisée pour détecter les types MIME, particulièrement la fonction PHP générique mime_content_type, qui échoue à détecter les fichiers PNG. Cherchez sur les web mime_content_type png pour avoir des informations sur la résolution de ce bug pour la version de PHP, peut-être en éditant votre fichier magic.mime.

See here for more info.

…is a search for a short keyword giving no hits?
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 est actuellement en développement, et n'a pas encore été mis en archive dans une version finale. Le code peut être téléchargé à partir de Subversion si vous voulez.

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

…can't I download MediaWiki {{#expr:{{MW stable branch number}}+.01}}?
MediaWiki 0000 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.

...ça ne marche pas ? Ça marche sur Wikipédia !
Wikipedia and other Wikimedia web sites use the current version of the code in development; at present, this is MediaWiki, pulled from the current development branch. Également, les sites fonctionnent avec plusieurs extensions, comme "Makesysop" et "Renameuser" (la liste complète existe dans la page de version de n'importe quel projet de Wikimédia).


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

…do I get logged out constantly?
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.

…doesn't my wiki work on Sourceforge?

 * See Manual:Installing MediaWiki on SourceForge.net.

…is it a good idea to keep user accounts?
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 mediawiki-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:



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.

Où puis-je obtenir l'extension anti-spam et comment puis-je l'installer ?
L'extension anti-spam des sites Wikimédia peut être trouvée dans Subversion. Pour les instructions d'installation, consultez le fichier README.

Comment puis-je utiliser $wgSpamRegex pour bloquer plus d'une chaîne de caractères ?
$wgSpamRegex est un puissant filtre pour le contenu d'une page. Ajouter plusieurs items de regex est parfois maladroit. Considérez le code suivant :

Cet exemple de code permet d'additionner facilement des items à la regex sans trop compliquer à chaque occurrence. Il montre aussi deux filtres populaires qui bloquent quelques unes des attaques de spam les plus courantes.

I'm getting a strange error. What now?

 * See if it is covered by Manual:Errors and Symptoms
 * Try to find out more about the problem, see How to debug MediaWiki
 * See the section below for information on how to contact developers and other knowledgabe users.

I tried that but it didn't work

 * 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 below 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 . 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.

J'ai une question à laquelle il n'y a pas de réponse ici. Où puis-je aller ensuite ?
Si vous avez parcouru toute la FAQ ci-dessus, vous pouvez essayer les endroits suivants :


 * Vérifiez les autres sources d'aide de ce site.
 * Recherchez sur ce site.
 * Search older documentation archived on Meta; Useful developer documentation remains on Meta.wikimedia.org in the category Pages to be exported to MediaWiki.org until the m:Meta:MetaProject to transfer content to MediaWiki.org completes
 * Search the web
 * Dig into the source
 * See the section below for information on how to contact developers and other knowledgeable users.

Still no luck. Where can I ask for help?

 * Post a message at Project:Support desk
 * Envoyez un e-mail à la liste de diffusion mediawiki-l
 * Demandez aux développeurs sur notre canal IRC (réseau Freenode, canal #mediawiki)
