No one has access to the server... When setting a new password in the file only PhpMyAdmin changes it's password so I get an error message. If I try to access the database using something else like Navicat using root/root it works altough the password file says something else (not Root).
After changing the password in home/admin/www, stoping and started the server again it kept working with the original password (root). Any idea how to fix this or is there any other way to change the password?
