This is quite common problem and I found a lot of tutorials to help me solve it, although, there is one additional problem with my case...
This is my config settings
Did you add a password to the MySQL 'root' userid?
If not, by default it comes without a password. So use
$cfg['Servers'][$i]['password'] = '';
and remove this its a defunct parameter since phpMyAdmon 3.2.0
$cfg['Servers'][$i]['AllowNoPasswordRoot'] = true;
