Server Error 500 on forums

[LiquidAtoR]

Hello,

I've experienced off and on server error 500 while trying to reach the forums.
The main page works fine, it's just the forums I get the 500 error with.
Soft and hard refresh doesn't seem to matter.

Some maintenance going on?
I can get on it at the moment, just disappears every now and then.

Kind regards, LiquidAtoR.

Edit: Might add I'm using Bluefox Fixed skin (seems you're changing things in em).
