I saw [this](https://stackoverflow.com/questions/18012052/how-to-log-in-to-phpmyadmin-with-wamp-what-is-the-username-and-password) thread.
it says I should set username to "root" and blank the password. but when I tried to do this, it says : 

> 
> Login without a password is forbidden by configuration (see
>  AllowNoPassword)
> 
> 
> 

Am I doing something wrong?
