I have a similar Problem. I can log in normally, do anything like changemode or map, but pressing "p" does not open any admin panel. If I copy this account.xml to my local computer and log in there with exactly the same account, I do have this admin panel. How can I fix that?
It would be more important to get that work on my root, because every five minutes there comes at least one cheater I would love to kick, but I cant.....isnt there any console-command to kick those players?
