Looks to me like there's a problem with your connection to the MySql database. If former web developer used old fashioned MySql connections and your server was recently upgraded to PHP 5.5, that might account for the discrepancy because MySql connections are no longer supported in PHP 5.5+. To confirm this yourself, create a new test.php page with the following code and upload to your remote server. Then view the results in your browser
<?php
phpinfo();
?>
