Since I have the IE9 version there is some problem with the compatibility view and my website. When the compatibility view of IE9 is turned on, every page is laoded for just a second and than straight goes into a 404 error. If I turn the compatibility view off all pages are loading just fine. Google Chrome has no such problem, but off course it should be perfect also in IE no matter the version.

What is going wrong and how to fix this? Can anyone help me with this?
