For some reason my header broke. Like this: http://www.obsessed-gaming.com/forum/
It's only when browsing the forum and nothing else. I haven't really done anything on the site, it just appeared for some strange reason. Also my node icons has gone all orange for some reason, I have checked the node icon style property and they're all set to transparent. I'm not very good at these things so any help is appreciated.
Thanks in advance / Totte
