Thread:Extension talk:ParserFunctions/Fatal exception of type MWException Error/reply (12)

I'm getting a lot of these on WP today as well. Everything worked fine yesterday. Example: "[7e0f687c] 2013-06-28 04:56:55: Fatal exception of type MWException".

I can load the main page and click on wikilinks, but clicking "View History" or doing any kind of search results in the above error.
