If you're sure the account manager is enabled in your config, look if you have an account manager in your database. If you have, check what the acc and pass is or change it to 1/1.
If not, you can try to add an account with acc/pass 1/1 and a player named account manager.
Edit: And again, stick to one thread. You now already have 8 threads about the same problem. This way it only makes it harder for people to help you.
It doesn't matter if it's a little different, if it's a continue on your previous problem you can just add it in the same thread.
