Some of you may have noticed when browsing the wiki a rather annoying problem keeps popping up. Every now and then, you'll get this message randomly (seemingly especially when editting):

Unexpected non-MediaWiki exception encountered, of type "Exception"

It's happening all over Wikia, and thus, isn't the fault of any new .JS or .CSS in case you were wondering about pelting stones at me. Unless my coding somehow managed to muck up all of Wikia.

The closest thing I could find to somewhere discussing it was this blog.
