Wordpress Themes - WP Forum at BFA - Homepage does not load because of rotation error

Problem: The homepage of basisschool-marcoen.nl is NOT loading in FF3.6 (IE and Chrome are working fine! no errors) I looked in the logs (see below) I do not use rotating headers so that setting is off in ATA. Can someone see what the problem is I did not see this before...

All the other pages are loading fine in FF and I can also login e.d. its only the homepage in FF thats has a problem

Thx! :)
