[RAC]

I am stuck in the install.php page

Required PHP modules
MySQL
Not available Failed

Here's my sql config in config.php

// MySQL information for L4D Stats DB
$mysql_server = "localhost";
$mysql_db = "l4d2stats";
$mysql_user = "root";
$mysql_password = "";
$mysql_tableprefix = "";

Let me know if anyone have any solution.
