Thread:Project:Support desk/Unable to upgrade 1.19.2 to 1.20

Hi, thank you for taking your time to read my plea for help. I just recently attempted to upgrade my website's MediaWIki installation from 1.19.2 to 1.20. I downloaded the files and replaced the old ones with the new. When I was then going to run the web updater, I clicked next on the first step (Where you select language) and I got an error page. Now when I try to return to /mw-config/ I get that error every time. This exact thing happened when I attempted to install the SocialProfile extension earlier.

My website is EpicNuts.

The error I get says the following in chrome "HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request."

In Special:Version is says that I am now running 1.20, but the web updater is still not working. I hope I have provided you with everything you need to help me and I thank you beforehand for anything you can do. Cheers!
