Fault on my Site subheader.php?

Hi all,
I founded a fault on my website yesterday.
This few days im trying to fix it, but would'nt fix.
Thats why im here for help.

This is the problem:

Yesterday i uploaded a theme to my site called '' Bluescape Theme.zip ''
I when to my admin settings, and enabled the theme.
After when back to main site, and everything was in order for now.

Later i logged out of my site, and saw this.
Check (screenshot) attachment.

The theme was very ugly, and site was mess up, when i was as guest on my site, (Logged Out)
To see for your own eyes go to: http://g-amefactory.be
I dont really know what's the problem, maybe cause i was playing with subheader.php, and maybe i put a wrong code in it, or i removed some kind of code? any thing is possible.

I also update my system, yesterday. maybe there was a fault in the update, and is what causing this problem.
I tried hard to fix, but dont work.
Can someone help me, cause when guest come on my site, they see the theme mess up.
But when log in as member, then is the theme normal and good?
Weird he?

Please help,

Greetings,
Nush :tup:
