Forum home page is sitting to the right

[V25RJB]

hey all,

i could really use some help with this if anyone can help.

My website url is www.xtremesniper.com/CMR

Basically tonight i have installed a couple of new themes and i have the same problem on both . The forum homepage is sitting over to the right and wrapping round on its self and coming back on the screen on the left {i hope that makes sense}.

I read on here that it may have something todo with the navbar but i cant find it anywhere {im a bit of a noob with this at the mo}.

I have checked the forum width and thats set correctly, This problem is only on the forum home if i go into any of the actual forums it sorts itsself out and goes back to how it should be.

i have attached 2 images aswell so you can see what i mean-:

1- error - This is how my forum hompage looks
2, Correct - this is how the rest of the forums look

Any help would be appreciated

Rob
