For normal users it is not possible to delete a version of an old page. Pages can only be moved, not deleted.

Administrators can delete version, so they can not been seen by regular users anymore. They're still stored in the database, but they can be deleted using the [[meta:SpecialDeleteOldRevisions|SpecialDeleteOldRevisions]]-extension.

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?===
 
−
 
 
−
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 toolbox.

===How do I reset a password?===
 
−
 
 
−
For security, the user password hashes include "salt" to make it more difficult for someone who somehow gets hold of the hashes to crack them all at once.
 
−
 
 
−
For compatibility with old (pre 1.1.0) installations set [[Manual:$wgPasswordSalt (section)|this]] to false.
 
−
 
 
−
 
 
−
To reset the password of users when this option is set use the following query:
 
−
 
 
−
UPDATE user SET user_password=md5(concat(user_id,'-',md5('mynewpassword'))) where user_name ='WikiSysop' ;
 
−
 
 
−
user_id is the userid of the user, mynewpassword has to be your new password and WikiSysop could be an other user.

Note: this is the public domain MediaWiki FAQ from 13 September 2006

Only,

Great site. Keep doing.,

Your Site Is Great,

Nise site,

Incredible site!,

Customising Further

How can I prevent editing by anonymous users?

As of MediaWiki 1.5 onwards, there have been significant improvements to user permissions settings which make restricting access to certain functions easier and more flexible. These are controlled by the $wgGroupPermissions configuration option.

For information on using this option, see the Preventing Access page on Meta.

Why...?

...is the Help namespace empty?

We don't currently have a clean, internationalised set of help pages under a free license. A few developers are hoping to make this possible; however, the Help namespace currently ships in a blank state. You are free to add your own help pages, or copy certain of the items from Meta, e.g. the user guide or MediaWiki Handbook, these two collections being free to use under the GNU Free Documentation License.

...are some of my images not showing up after an upgrade?

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 unknown / unknown and, in some cases, a warning about potentially dangerous files.

The cure for this is to run the rebuildImages maintenance script from the command line. This sets the MIME types for all files in the database, and should restore things back to normal.

...are all PNG files not being turned into thumbnails?

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

The default settings for mysql demands that the minimum length of a word to be indexed for fulltext search is 4 characters. This can be a problem if you want to search for shorter words as substrings in pages. To change this, you need to reconfigure your mysql, as described in the MySQL documentation note that indexes must be rebuilt after resetting the mysql default settings.

...can't I download MediaWiki 1.8?

MediaWiki 1.8 is in a development state at present, and has not been packaged into a general release. The code can be downloaded from Subversion if desired.

...doesn't this work? It works on Wikipedia!

Wikimedia web sites run the current alpha code, MediaWiki 1.8. See above for caveats and information on obtaining this.

Also, they work with several extensions, such as "Makesysop" and "Renameuser" (the complete list exists in a version page of one of their projects.

...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.

Anti-spam

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

The spam blacklist extension can be found in Subversion. For installation instructions, consult the README file.

How do I whitelist domains from the spam blacklist?

You can list the domains you wish to whitelist on your local [[Mediawiki:Spam-whitelist]]-page.

For the format you need to use take the whitelist of the English language Wikipedia as example; wikimedia:w:en:MediaWiki:Spam-whitelist

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

$wgSpamRegex 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.

Where Now?

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

Bugs and feature requests should be posted on MediaZilla, our implementation of Bugzilla. Please search the database prior to posting, to avoid creating duplicate entries.

I have a question not answered here. Where do I go next?

If you've exhausted the FAQ above, please try the following:
