MediaWiki installation recommends PHP 5If you are trying to install MediaWiki and during the installation the script says that your PHP version must be 5 in order to proceed, you can resolve this issue by:
A) download one of the previous versions of MediaWiki, which is compatible with older versions of PHP (version 1.6 is the last one that supports PHP4 )
B) You'll just have to login into your Customer Area -> Get Support and by posting your ticket you'll have to request that we upgrade(move) your account to a server with PHP5.
IMPORTANT NOTE: Bear in mind that if you have any applications that are using PHP4 and this is their exact requirement, they are not going to work properly on the server where your account will be transferred.
