PHPMyAdmin and Root Login
If you're trying to login via PHPMyAdmin as the root user, it will NOT allow you to login from a remote IP address. This is the way it was designed though! In an effort to improve security, EHCP Force Edition by default does NOT allow remote logins for the root user via PHPMyAdmin. However, you can login using PHPMyAdmin from the local server.
