 * Noticed this plugin was inactive. When I tried to activate it I received a fatal
   error message below;
 * Plugin could not be activated because it triggered a fatal error.
 * Fatal error: Cannot redeclare _eventorganiser_set_constants() (previously declared
   in /home2/leisureg/public_html/inside/wp-content/plugins/event-organiser/event-
   organiser.php:49) in /home2/leisureg/public_html/inside/wp-content/plugins/event-
   organiser-org/event-organiser.php on line 58.
 * Can someone please help me with this.
