Check with your server provider - it seems that MySQL server was down at that time.

One of the reason for such kind of error is wrong database information in configuration.php file such as:

Code: Select all

public $dbtype = 'mysqli';
public $host = 'localhost';
public $user = 'root';
public $password = 'root';
public $db = 'test';
public $dbprefix = 'testdb_';


Check the database information such as host ,user ,password ,db ,dbprefix are correct.
You can check it in phpmyadmin.

For example if you provide wrong password above you will get this error.

The password reset thing in configuration.php did it for me. Thanks all.
