[xwiki-users] Error while parsing velocity page Wrapped Exception

Hello, after editing the parant of a page I do get the following error on every single page, execpt the log in. Therefor I think maybe one of my panels has issues. Is there a way to disable those. Or any other ideas what might be wrong?
