I was developing a new drupal 7 site on a local WAMP server.
Using phpMyAdmin, I tried to remove privileges to the site from an existing user and I guess succeeded in removing privileges from the 'root' user.
Now I can't get into phpMyAdmin anymore instead I get this:
"Error: #1045 - Access denied for user 'root'@'localhost' (using password:" YES)"
"phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server."
