@Ruben: I dont have the problem with the "new class moderator".
I uploaded alle the files (from version 7.5.7) to my server again and set the permissions (directory 0777 + files 0666) like the upgrade guide said.
The problems still exist and I can not run the upgrade.php again because I already did it some days ago.
I uploaded the styles/common.css and styles/admin.css files too.
Was this a mistake ?
Is it possible to run that upgrade file again anyway ?
