Messed up with cluster server and user add!

Hey there,

I tried to add a cluster server to add second server.

I started cluster server on main server, then i added user or smth, and every privilege is gone from webmin/virtualmin.

Now when i log in my account with root password of my server, all menus are gone, only webmin with a search box and system information appears in window.

How do i restore back all my privileges?

I get this error Access denied : User "my login name" is not allowed to use the Webmin Configuration module.

I think i added root user on cluster server. Or i don't know what happen.
