ISSUE SUMMARY:
We had to change all rights on the server to 644 (755 for folders) because of a virus that kept coming back, no matter what we did. Everything seems to work fine, exept that users can't upload new profile pictures. I set the folder "root/images/avatar" and all contents to 777, but it still didn't change anything. Could someone help us?
Yes, you entered the Joomla username and passwort in the FTP. ;) But the problem is solved anyway, since we found a error in the .htaccess which was causing the problems. Thanks!
