Thread:Project:Support desk/Upgrade (2)

Hello, I believe that I have MediaWiki 1.12 but need to confirm this. If the page is broken, how can I verify the version?

Since I upgraded to PHP53, the MediaWiki no longer works. Is there an easy fix for this? I need v53 for other aps that I am running. I know I need to get my version upgraded and will need to know where the archive for the older version of MediaWiki is located and any instructions for upgrading too. Thanks for the help.
