IE cannot display webpage
 

I got the weirdest problem. I'm using IE7 (but it happens in Firefox too) and can't stay on my own message board, I get the message IE cannot display the webpage when I want to move around the board. The weird thing is I can get everywhere else (other sites) just fine. Anybody got any info that might help me out?

And no, no one else is having this problem at the site.
