PHP 4
MediaWiki requires PHP 5. If you are using PHP 4, upgrade now! It's no longer supported by the PHP group, and has lots of bugs.

Many shared hosting providers offer both PHP 4 and PHP 5, running simultaneously. Ask your provider if they can do this.

If for some reason, you really really need to run MediaWiki on PHP 4, you should use the MediaWiki 1.6.x branch from 2006:

Old branches
If your MediaWiki installation is heavily modified, it may be difficult to incorporate the latest official changes to MediaWiki. To support such users, we maintain old branches of our code for up to a year.


 * Download old MediaWiki

Archive
You can find downloads of all versions of MediaWiki back to February 2007 on our download server:

Even older versions can be found in Subversion, in the tags directory.
