@Nono Without going through the web interface you can check the file in /var/www/fog/lib/fog/system.class.php.
Toward the bottom of the file there is a line that start with define('FOG_VERSION'

@nono The values in fogsettings should remain as the installer created them. As I said the fogstorage account is for external access to the master fog node from storage nodes. That account only has edit rights to the database, it can’t create or delete tables or schemas, that is the function of the fogmaster account. If you change it to fogstorage your next fog upgrade will fail because it doesn’t have the right access level to update tables in the fog database.

@Nono Marking this solved as well now as I finally found the root cause of it and added a fix to the installer (ref).
