You need to turn off custom errors in web.config to display real error message:

        <customErrors mode="Off"/>

Problem with this resource. It can not be displayed. This errormessage comes in german, I had to translate it.

Errormessage: There exists an open string. Line 14100, position 81st

Is there an error in the xml-files?

That's a fair possibility, you could try systematically replacing batches of posts, failing that work through any extensions, disabling and enabling.

I think I fixed it.

The problem was the PostView.xml-File. This one was corrupt.

Thanks for help.
