I installed wamp server2 it didn't have password and it had this error below then I went to mysql and set the password for root with this command and I can login using this password but again I can not access phpmyadmin.I restarted the services too.

update user.mysql set password=password('root') where user='root';

then i went to config.inc changed the pass to this one:

$cfg['Servers'][$i]['password'] = 'root';

again I restarted and again no result.

the phpmyadmin page:

Welcome to phpMyAdmin

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.

config.inc:

<?php

/* Servers configuration */
$i = 0;

/* Server: localhost [1] */
$i++;
$cfg['Servers'][$i]['verbose'] = 'localhost';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'root';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

/* End of servers configuration */

$cfg['DefaultLang'] = 'en-utf-8';
$cfg['ServerDefault'] = 1;
$cfg['UploadDir'] = '';
$cfg['SaveDir'] = '';


/* rajk - for blobstreaming */
$cfg['Servers'][$i]['bs_garbage_threshold'] = 50;
$cfg['Servers'][$i]['bs_repository_threshold'] = '32M';
$cfg['Servers'][$i]['bs_temp_blob_timeout'] = 600;
$cfg['Servers'][$i]['bs_temp_log_threshold'] = '32M';


?>

It was firstly this line $cfg['Servers'][$i]['password'] = ''; setting allow to false and restarting will not change the error either with the help of Erika I understood that it can't read confg.inc file how to make it read from this file?
