Thread:Project:Support desk/Internal Error - Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.

This text I see when i try to upload a picture or add a picture from the commons. I use MediaWiki 1.19 and the webspace is cwcity.de. What's wrong? Greetings (Url to the wiki: http://baustelle-ds.cwsurf.de/index.php?title=Hauptseite)

Edit:

If I disable Instant Commons, I can upload pictures.
