Website bug: 402 bad gateway

[renegadeofunk]

For some reason I get a 402 Bad Gateway whenever I try to view a new post in General. Only visited posts are working for me (i.e. the link isn't bold on the list). Also because those links don't actually seem to turn visited for a while after I clicked them that means I can't view new forum posts.

I tried logging out/in to see if that would turn the links visited but the page which performs that action gives a 402 Bad Gateway as well so I'm actually unable to log myself out.
