Thread:Project:Support desk/Can't use PHP 5.3, which wiki version can work on 5.2?/reply

Hi!

MediaWiki 1.19.x is the last version, which runs on PHP 5.2.

Your website and MediaWiki should basically use the same PHP version. But your provider might give you the possibility to set the PHP version separately for each domain, so that in this case you could have your website use PHP 5.2 and your wiki PHP 5.3.
