I wish it were that simple, I checked that already. I have one rule to get rid of index.php, and a list of exceptions for my images, css, etc. I added "error" to the list, and the normal 500 server error message appears. I changed it back because that doesn't help much. That's the only change I've made to it since I set it up about a month ago.

I feel like (read: hope) that it's just some dumb error that has a quick and easy fix. But I'm not so sure. The $_SERVER variables are delivering an error message.. that seems to be a bigger problem :-S
