 * Recently updated to version: 3.7.1
 * I tried to delete a series of an event and received these errors (the events 
   were deleted):
 * > Warning: Trying to access array offset on value of type null in _**/**_***/***/***/
   > wp-content/plugins/my-calendar/my-calendar-event-editor.php on line 559
   > Warning: Trying to access array offset on value of type null in _**/**_***/***/***/

   > Warning: Undefined variable $type in _**/**_***/***/***/wp-content/plugins/
   > my-calendar/my-calendar-event-editor.php on line 823
 * Should I be worried?
 * Thanks!

 * Nothing particularly to be worried about, assuming your delete action actually
   did happen. It’s a bug, and I’ll get it resolved, but not a major issue functionally.
