When I changed it to basic style, it looked like what was in the picture up top but with a white background. So I went into the forum layout option in my profile and changed it to the default layout. It looks better than it did before. I do not think it has anything to do with any changes RBCP made to the forums. Other websites display normal after I upgraded my browser.
I'll stick with the default layout until Firefox makes v4.0.1 compatible with the boards. If it's my settings, I'll play around with this weekend.
Speaking of layouts, whatever happened to the orange color layout that was around in 2006 or 2007. Can't which year it disappeared?
