place..when i am trying to open the page as
http://localhost/phpmyadmin/
it give me following error:

but when i am opening same as
https://localhost/phpmyadmin/
it open successfully..i have check the config.inc.php file it has
following setting..
/* Authentication type and info */
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
Does anyone know what could be the problem..i have tried almost everything
