This morning I wake up and all my members are freaking because the site isn't loading. So I go and take a look... It says:

PHP Code:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'a7155846_zxc'@'localhost' (using password: YES) in /home/robynswo/public_html/inc/functions.php on line 95
Error connecting to MySQL 


Then I go look at my config file and it says:

PHP Code:

<?php
//Mysidia Adoptables Site Configuration File

$dbhost = 'localhost';              //DB Hostname
$dbuser = 'a7155846_zxc';            //DB User
$dbpass = 'testeo123';            //DB Password
$dbname = 'a7155846_zxc';                //Your database name
$domain = 'silvadopts.com';                //Your domain name (No http, www or . )
$scriptpath = '';        //The folder you installed this script in
$prefix = 'adopts_';                

?>

It's like someone completely changed my info. Did I get hacked? And if I did, how do I prevent this?
