 * Hi,
 * I’m running Elementor, and this plugin is causing problems. If I try to save 
   a page edit in Elementor where the shortcode for this plugin is present, I get
   the following error:
 * [09-Dec-2019 16:52:09 UTC] PHP Fatal error: Cannot redeclare OWAC_check_date()(
   previously declared in /home/xxxxx/public_html/wp-content/plugins/availability-
   calendar/public/includes/frontend.php:25) in /home/xxxxx/public_html/wp-content/
   plugins/availability-calendar/public/includes/frontend.php on line 25
 * If I disable Availability Calendar, the page saves fine.
 * Any idea why this error is occuring. I’m on PHP V7.1 right now.
 * Thanks
 * Bob

   experiencing the same problem.
 * Thanks.
