Thread:Project:Support desk/MediaWiki 1.22.0 upgrade triggers HTTP 500 Internal Server Error/reply (6)

I have been experiencing this issue after upgrading from 1.21.3 to 1.22.0 as well.

I have even tried installing a clean installation of MediaWiki 1.22.0 with a new database, no third party extensions or modified settings. I still get the same result of a blank page while waiting for the site to load followed by a 500 error.

It seems a change between 1.21.3 and 1.22.0 is causing incompatibility with some webhosts.
