I only get that when I'm hacking into the server.
Just kidding.
Seriously, though I have a different issue that shows up when the forum starts slowing down. Sometimes when I click on a section or a thread, it loads the page but most of the page is programming code, not the pretty forum we're used to.
When it happens, I just hit F5 to reload and it goes back to normal. Does anyone else get this problem?
