yeah, index broken for me aswell,
had quite alot of trouble getting into this thread,

where's my $10?! and im not taking the 2nd bet, just so you know.

Didn't try this because I thought it wouldn't work...but I didn't remember the exact URL aswell anyway. Thanks =)

Fixed it.

Good job :)

If you don't mind disclosing, what was the problem and why did it exist?

My favorite part was when it felt like the forum was collapsing.

u r the culprit

Betting on a full hard drive.

Probably related to this.

And how exactly would that happen without the tmp directory either being deleted, having permissions changed, or filling up?

I agree with Loriel's speculation.

I have no idea, but the error message is identical.

I doubt it, though from what I heard Stefan did have to backup the forums, so it's possible he moved them to a new web server or something. I doubt it, though, since it's hosted on the same site as the main website.
