on the director page, you are using the "Log in success" access rule, you should be using the "Logged Into <Your User table>" (where <Your User table> is the name of your user table) access rule instead.
this problem will happen in any page that you have both CMS content and security assist.
to correct the error, you will need to manually comment the ../WA_SecurityAssist/Helper_PHP.php require once line:
//require_once( "../WA_SecurityAssist/Helper_PHP.php" );
