Anyways, everything should be fine now. Almost all of the errors reported over the past 48 hours are the direct result of me doing work on the site. I finally managed to narrow the problem down to the text link ads on the front page.
My apologies for all the errors everyone got as I know it was annoying, but everything should be working great now. If you are still getting problems, check out the first post of this thread and try those steps.
