When using phpMyAdmin you may notice that when you log out using the "exit" button you get the following error message:
Welcome to phpMyAdmin, Wrong username/password. Access denied.
This behaviour of phpmyadmin is normal and it has been doing this for a while. We have asked Cpanel to change it so that it just simpy says You are now logged out or something just as easy to understand but I guess they have bigger issues to deal with. If you do see this message then it simply means that you are logged out.
