This could happen for several reasons:
- $cfg['Servers'][$i]['controluser'] and/or $cfg['Servers'][$i]['controlpass'] are wrong.
- The username/password you specify in the login dialog are invalid.
- You have already setup a security mechanism for the phpMyAdmin- directory, eg. a .htaccess file. This would interfere with phpMyAdmin’s authentication, so remove it.
