Thread:Project:Support desk/MediaWiki 1.22.0 upgrade triggers HTTP 500 Internal Server Error

Hi. I'm using MediaWiki and upgraded it several times without any problems. On the weekend I tried to upgrade from 1.21.3 to 1.22.0. Firstly I used the web installer to do so. I got no error messages, but as soon as I tried to load my wiki I got an HTTP 500 Internal Server Error. I tried different browsers and even waited several hours. After that I downgraded to 1.21.3 - everything worked fine again. I retried this three times, using the web installer and update.php script without success. The loading time is about 30 seconds until the 500 error occurs.

Finally I downgraded again and the wiki is functional with 1.21.3. Does anybody have an idea or similar problems?
