Site gone when logged out?

I installed ibproarcade this morning, and everything seems to be working fine when logged in. But when logged out, only the banner and the navbar shows, and none of the links are working exept from faq, that looks really weird!

Take a look

www.motorcykelforum.dk/forum/faq.php and at the mainpage www.motorcykelforum.dk

Any suggestions? Im pretty lost, i only been admin for 3 months so im still a newbie

Solved!

Problem solved, was just a broken line in navbar template! Got me worried there for a moment!
