Erro no webcindario (miarroba)

Coloquei um site no webcindario (miarroba)

mas na hora que tento conectar ao BD retorna a seguinte mensagem:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/webcindario/ohow/Codigos/Php/ConectarBD.php on line 7

Warning: mysql_select_db(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/webcindario/ohow/Codigos/Php/ConectarBD.php on line 8

Warning: mysql_select_db(): A link to the server could not be established in /home/webcindario/ohow/Codigos/Php/ConectarBD.php on line 8

?>

Warning: mysql_query(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/webcindario/ohow/login/logar.php on line 22

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

O arquivo .../Codigos/Php/ConectarBD.php está da seguinte forma:

<?php

//Conecta ao banco

	$hostname_caf = "localhost";

	$database_caf = "ohow";

	$username_caf = "ohow";

	$password_caf = "******";

	$caf = mysql_connect($hostname_caf, $username_caf, $password_caf);

	mysql_select_db($database_caf);

?>

Já tentei colocar o $hostname_caf como "mysql.webcindario.com", "localhost" e "216.66.18.60", mas deram o mesmo erro.

A configuração do BD está da seguinte forma:

DATOS CONEXION MYSQL

Servidor: mysql.webcindario.com

DB: ohow

Usuario: ohow

Contraseña: ******

Alguém sabe como faço pra me conectar?
