 * Hi There,
 * I installed this plugin as we are using the Joomla version of this for our old
   site. Since we migrated to WordPress, this became the best option for the same
   function since it came from the same developer.
 * However I’m getting problem using this, on the page where I put the shortcode
   it just shows a blank page, below are the error messages when in debug mode.
 * Also to give a background on my installation, just in case you can advise if 
   it’s what causing the problem?
    *using this in a Multisite environment. *my main
   admin username is changed but the id is still #1 *I left the default setting 
   and went ahead to use the shortcode.
 * Error messages on the page where the shortcode is used.
 * Notice: Undefined index: def_visitor_level_strict in /var/www/html/mydomain.com/
