Today I figured out, that a member can't edit his profile (in the backend) if he doesn't have access to the Site-Content area of the CMS. I can't find the problem in the code but perhaps you can. myprofile() on Leftandmain.php simply loads the whole backend again within the greybox and not the form as it should. Perhaps there are problems while rendering with a blank page. Can anyone look for that error?
Thanks.
