I'm curently installing my Wordpress website in local. I've created a database called 'wordpress'. But during installation, an error say 'Impossible to select db'. BUT, the database exists into my phpmyadmin interface.

The current username has all privileges and the hostname is set to 'localhost' (not %).

I really don't understand ? Wordpress say to me that it successfully connected but can't retrieve the db. My current user doesn't have password.

Any ideas ?
