Try to add a value to the database.
Login to ou phpmyadmin, find the table `ow_base_authorization_permission`.
Open your admin panel i firefox or other browser that you can "Inspect" values in code.
Open "User roles", inspect element "view" for users. (se photo.)
There you see a value in code.
Then you can insert a new row in the table with "roleid" = 1
Hope you understand this.
