Yeah that's how it should be.
I think I may have fixed it. I read up on it and it's an error in the forum skin apparently. My settings were to show the website as '986 Forum vBulletin 3 Style' in my settings, rather than 'Forum Default'. I switched it to Forum Default (which is still the 986 style), and it seems to have worked.
I'll let you guys know in a day or two if it's still working
