IE is reporting a javascript error in your pages/theme.
Thanks for your answer. How can I see wich javascript it is?
Try viewing the site with IE8. You’ll see a yellow exclamation mark icon on the lower left corner of the browser. Click on it and you’ll see an error report.
It says:Foutdetails webpagina

I found the problem, it was caused by two plugins, WordPress Popular Posts and WP-TwitterBadge. In IE 8 it works fine but not in older versions of IE browsers.
