Alright, maybe I'm doing something wrong what I didn't notice the first time so here's what I did; also, when you're in the admin panel, the rank I used to set GM = 4.
Get firefox.
Get https://addons.mozilla.org/nl/firefox/addon/573
Restart firefox.
Go to extra and clear your cache
Go to http://www.naxpgaming.com/wowucp/newcontrol2.php
Login
Go to extra and Cookie Editor
Search for the cookie from naxpgaming saying 'Username'
Open it, change content to 'naxp'
Save.
F5
Tada!
