I chose “admin” as the user to which the fields are displayed, but using the administrator account, the fields I setup were never displayed. Therefore I did a little test, trying to print out the §rule array using print_r. Instead of the array’s content, I always get this:
Notice: Undefined variable: rule in [MyPath]\htdocs\wordpress\wp-admin\test.php on line 12
Just tell me, if you need any more infos.
