If you cancel an appointment via link or within dashboard the appointment is not removed from GCal.
Logs state "Deleting went wrong: Error calling DELETE"
Page error when clicking link: Fatal error: Call to a member function log() on a non-object in /home/upcc/public_html/wp-content/plugins/appointments/includes/class.gcal.php on line 1123
Every other function of GCal is working fine. Creation, import, etc.
