phpMyAdmin cannot connect to MySQL server

Question

I really need help to fix this error, because next Monday is my final year project presentation, please. I don't know how to fix this.

I've try to follow this http://www.ishaanrawat.com/solved-wampserver-1045-access-denied-for-user-rootlocalhost-using-password-no/ instruction, but I get the same error.

And, a few minute ago, I uninstall wamp sever, in hope after installing it again, I can use my wamp server normally, but still the same error.

Below is the error:

MySQL said: Documentation

1045 - Access denied for user 'root'@'localhost' (using password: NO)

phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

p/s: this is Vietnamese video :)
in config.inc.php you edit folowing code:

* First server
 */
$i++;
/* Authentication type */
$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//uncomment this
$cfg['Servers'][$i]['auth_type'] = 'cookie';
//comment this
//$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

then exit wampserver, reopen wampserver, open PHPMyadmin, you'll show login form :)

Go to phpMyAdmin folder inside of XAMPP or WAMPS server and open config.inc.php file. And Change username and password to set in your db.

 /* Authentication type and info */
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
$cfg['Lang'] = '';
