Manual:FAQ/oc



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

Ont pòdi joscargar MediaWiki ?
Click here to download the latest stable release of MediaWiki. Files are supplied in a .tar.gz archive. MediaWiki peut aussi être obtenu directement à partir de notre référentiel Git.

Consi pòdi enjaçar 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. See, where you will also find the minimum system requirements.

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. The MediaWiki development team refers you to your Linux distribution for assistance with installing, configuring or using them. 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.

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 :


 * You install multiple instances of MediaWiki (such as with a software bundle like the Bitnami MediaWiki Stack); in different directories – one for each wiki

Or


 * Vous utilisez une base de données différente pour chaque wiki

OU


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

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

Pour plus d'informations sur la configuration d'une famille de wikis, voir.

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.

How do I install an existing wiki, like Wikipedia or Wiktionary?
The main (but not necessarily the easiest) method is to import. See Wiki importing, below.

(Non-MediaWiki methods, such as Xowa and Kiwix can be found at w:Wikipedia:Database download).

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 for information about installing and writing extensions. See to find existing extensions.

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

Comment puis-je permettre le téléchargement ?
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 de téléchargement (par défaut ) 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  à   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.


 *  See also: 

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 . 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 :

"File is corrupt or has an invalid extension"
Some users have reported that after adding a file format to the allowed extensions list, an error is encountered. The text of the error is similar to the following:


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

Possible solutions:


 * Set the value of , e.g. under Unix or Linux, this would be

How do I change default user preferences?
The MediaWiki default user preferences are in  Don't edit that file, just use it for reference.

Say if you want to hide minor edits in recent changes by default. DefaultSettings.php says:

To change the preference, put this in your LocalSettings.php:

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

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 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 hideminor --old 0 --new 1

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?
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.

How do I edit the wiki's CSS?
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?
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 variable, which is defined in. This location is relative to the web server root and not the system root. Redefine this in 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)

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 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.

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 setting in LocalSettings.php and add

See 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 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 you would like to hide the title of a "Main Page" in a specific namespace like "Help:Main_Page" add the following to on your wiki:

Note the difference:  in comparison to. 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  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
 * 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.

Comment puis-je changer le texte de l'interface ?
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.


 * 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

Exécutez le script de maintenance rebuildMessages.php pour reconstruire l'espace de nom MediaWiki.

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 extension, which can make your wiki multilingual.

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

How do I remove the "Talk for this IP" link at the top right (e.g. when is true)?
One option is to hide the link using the following CSS in the wiki page MediaWiki:Common.css in your wiki:

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

How do I remove the "Create an Account or Login" link at the top right of the screen?
To remove the login / create account links from the personal_urls you can use this code in your to hook in and remove them:

How can I suppress actions and special pages?
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 https://www.mediawiki.org/wiki/Special:MyLanguage/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:, 

How can I edit / remove the Powered by MediaWiki image (and possible other images) from the footer?
You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css:

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

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 ' documentation.

How do I add a reply link to default signature tildes ( ~ ) template?
You can customize signatures in 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 their signature in 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  in your LocalSettings.php.

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 configuration setting.

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

 *  See 

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

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 the CSS files coming with the MediaWiki source code. For more information, see.

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

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.

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
 * 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.

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

Existe-t-il des tutoriaux à propos de l'édition ?
Il y a plusieurs tutoriaux sur l'édition, la plupart sur les projets Wikimédia, tels que Wikipédia. Il y a aussi des références de syntaxe, etc. disponibles sur Meta.


 * The page Help:Editing pages on this site
 * Aide de Meta en anglais : Editing

Comment puis-je avoir un format imprimable de la page ?
MediaWiki inclut des feuilles de style qui donnent automatiquement un style approprié à une page pour l'impression ; en utilisant la fonction d'impression ou de prévisualisation d'impression du navigateur, celle-ci doit rendre la page dans un format imprimable.

Vous pourrez aussi voir le format imprimable en utilisant le lien Version imprimable de la boîte à outils.

How do I use templates?

Yes, this is encouraged through the use of.

How do I use a template as a signature?
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.
 * 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 install the extension.

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 extension; there's extensive documentation.

Importing from MediaWiki XML dumps

 *  See: 

Importing from other types of wiki software
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

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, , or sometimes. 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
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. 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.
 * If you're starting from scratch or you're switching from one wiki to multiple, you can use and  to have all wikis share the user table of the "main" wiki.
 * If your wikis are already established and you want to switch to a single sign-on, you can use the extension.

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
 * Edit the source code of the relevant file(s) to fix the problem
 * Follow Gerrit/Tutorial

How do I add meta tags?
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.' );

...l'espace de nom Help de ce site est-il vide ?
cependant l'espace de nom Help est encore en construction. 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. 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 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.

...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  (inconnu) et dans certains cas un avertissement concernant les fichiers potentiellement dangereux.

La solution à cela est d'exécuter le script de maintenance  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.

Recent versions of MediaWiki implement responsive images. Due to a bug, if the server locale is set to one that uses commas instead of dots for representing a decimal point, images may not render on some browsers/devices. This can be confirmed by inspecting a thumbnail of a medium or big image on a page with the browser tools, looking at the HTML code, and see if the  attribute contains commas instead of dots when representing the   value.

...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.

…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 (GitHub).

...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. 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
 * You may also be missing several that are installed on Wikipedia, see #Templates imported from other wikis (such as Wikipedia) don't work for me

…do I get a 403 Forbidden error after setting permissions on my Fedora system?
Fedora Core enables by default. Instructions for setting SELinux permissions for MediaWiki are available.

…do I get Installing some external dependencies (e.g. via composer) is required?
Many web hotels only handle zip archives, and we only provide gz compressed tar archives, thus the archives has to be recompressed before uploading. This should not be much of a hurdle, but it seems like some archive tools occasionally fails to include all files in large archives. When this happen the vendor folder is left out, leaving the user with the rather non-explanatory error message.

Use a command line tool when recompressing the tar archive into a zip archive.

…do I get logged out constantly?
This is probably related to cookies or session data. See Log in problems for information.

If this is happening constantly to all users, it probably means that caching is misconfigured. Setting  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.

…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 this 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:



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 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.

is also useful.

…is the number of pages so low on Special:Statistics?
By default, is set to. This means the number of "Content pages" on the Special:Statistics page only counts pages which include at least one internal link. This can be changed by setting  to. Afterwards, run and/or. (On Wikimedia websites,  is run on the 1st and 15th of each month.) There might still be wrong behavior, see for example T212706.

Où puis-je obtenir l'extension anti-spam et comment puis-je l'installer ?
The spam blacklist extension can be found in Git, just like all other officially supported extensions. For installation and configuration instructions, consult the file and  over here.

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:

Upload it into your web directory and invoke it with your browser. Check the document root and the path to php.ini. Did you create a duplicate entry in php.ini? Add new settings to the end of LocalSettings.php, not to the beginning. Ask your hosting provider.
 * 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.
 * Were you editing the right part of the file?
 * If you created a .htaccess, are you sure AllowOverrides is on?
