Part of my header not showing up

[excalibur300]

Hey i was sent here by incadude, saying that someone here would help me.

I have the latest versions of Mkportal and MyBB.

Ok here is my Problem, On my portal page only part of my logo shows up not the rest, but on the forum it shows up fine. It only does this on certain themes, (those that require a  background file) and no matter what we can't figure out how to make them show up.

Thanks.
