Forums → Support Forum → 500 Error in Category Pages

Whenever I go to a category page other than page 1 sorted by date, I get a 500 error that looks like this:

In case it matters, links to category pages don't use URL parameters (anything after a question mark), but other pages in a category have a sort= parameter unless sorted by date, and a page= parameter. The first page sorted by date works with or without the page= parameter.

Is something being done to the category pages, or are they just (mostly) down?

Edit: The Shooting category is starting to work. So far, I've gotten the first 2 pages sorted by date and the first 3 pages sorted by rating.

Edit 2: My profile also gets a 500 error. I'm not sure if it's the same problem as the one originally reported, but I thought it was worth mentioning.
