the supper admin security rule uses variables that are created by the WA_Globals/WA_Globals.php file, you need to include the require once line to attach that file:
<?php require_once( "../WA_Globals/WA_Globals.php" ); ?>
before the WA_SecurityAssist/Helper_PHP.php, line 1 - 3 should be:
<?php require_once('../Connections/PowerCMSConnection.php'); ?>
<?php require_once( "../WA_Globals/WA_Globals.php" ); ?>
<?php require_once( "../WA_SecurityAssist/Helper_PHP.php" ); ?>
