Invalid Redirect

I tried to load the forum from my PC (windows 7 64bit, latest Firefox) and the Top 10 new posts didn't appear, thought that was strange so I looked around the page and noticed I was logged out, also strange. So I log in, then get this. Not really a problem for me, I just closed and reopened the forum in a new tab. Just a heads up. Also...numbers seemed to have a problem in the lower left corner. Since I reloaded the page that was fixed, which makes me pretty sure the problem was with my Firefox. But wanted to see if anyone has had a similar problem.

Yeah, this happens to me every so often. When it comes up as "not logged in", and I KNOW I am logged in, then I just close that page and open a new browser window (my default page is Mazdaroadster.net FTW).
