PHP Code Displayed when running the blog

Hi,

I have the WP files loaded on a NAS (Network Attached Storage)drive which is accessed from two servers (load balancing).

The page loads from one server, but no from the 2nd server.

Any ideas???

The 2nd server displays just the code, instead of loading the page:

<?php
/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */
require(‘./wp-blog-header.php’);
?>

Thanks.
