My Site Crashs on Internet Explorer

[benHammer]

Hey everybody,

i accidently found an issue with one of my sites - I didn't check the other ones by now.

HUGE problem:
My site http://schokoladeselbermacheninfo.de crashes on Internet Explrer (V8). Homepage works perfect, but as soon as I click on a content page the Internet Explorer closes tab and tries to re-open it 2 times.
Then I get a error message with a BIG red cross which tells me that I'm not able to visit this page.

Could someone please have a look at it with Internet Explorer??
Chrome and Firefox work perfectly.

I really don't know where to start fixing...
Thank you so much in advance!!
