My forum will not display centered on the page it always shows left in IE8

[jmille44]

IE8 displays my forum left justified and not centered on the page.

I have installed Global Headers version 2.0 and running SMF 2.0 GM.

When I remove the GH code from subs.php the forum is centered again. 
Does anyone know how to fix IE8 from displaying the forum left justified instead of center when you have
GH installed?

Thanks!

I suggest you ask the author of the mod about this. Apparently the mod has invalid markup, which I suspect is what is causing the problem.
