Thread:Project:Support desk/PHP version error when upgrading from 1.17 to 1.21/reply (11)

Hi!

No, I'd say you cannot update MediaWiki in a way so that new versions become compatible with PHP 5.2. Even MediaWiki 1.19 (which would be nice for you as well as it has long term support) already requires PHP 5.3.

What is possible would be to do what some webhosters do: Set up two different domains, one for your forum and one for MediaWiki, to install both(!) PHP versions(might not be that hard - what you write it sounds like you somehow already have both) and two configure them separately. That would enable you to use PHP 5.2 with the forum and PHP 5.3 with MediaWiki. However, I have never done that myself and I can't tell you how hard that really is to accomplish.
