The error that I get on phpMyAdmin is the following
The phpMyAdmin configuration storage is not completely configured, some extended features have been deact
This happens because the current account you have used to log in probably has very limited priviledges.
To fix this problem, you can change your the AllowNoPassword config setting to false in config.inc.php. You may also force the authentication to use the config file and specify the default username and password .
$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = ''; // leave blank if no password
After this, the PhPMyAdmin login page should show up when you refresh the page. You can then log in with the default root password.
