 * Hey
 * I’m using your awesome plugin but unfortunately I’m getting a 510 response from
   the server when trying to update the calendar.
    (failed to load resource: the
   server responded with a status of 510 (Not Extended) … admin-ajax.php) Any suggestions
   what I’m doing wrong?
 * Greetings
