I assigned a password to the root MySQL user in XAMPP some times ago. I recently tried to undo that and give it no password but it's not working.
I tried setting the password to an empty string using mysqld --skip-grant-tables and then using the mysql command line directly. It looks like it works, the root user no longer has a password, however if I login in PhpMyAdmin I cannot see any of my databases, only an "information_schema" and a "test" database. If I look at the User tab, it seems to have all the privileges though:

Any suggestion on how to fix this issue?
Note: I checked with the command line, all my databases and tables are still there, I just cannot see them in PHPMyAdmin.
