If I leave our existing feeds alone and do not edit anything settings, they seem to display alright.
If I edit a setting, then I get “No events to display.” even though there are plenty of events in the feed.
If I turn off “Expand Recurring Events?” then I get the same problem as stpeterstallahassee:
Warning: date() expects parameter 2 to be long, string given in /home/content/C/h/a/…/html/wordpress/wp-content/plugins/google-calendar-events/includes/class-gce-event.php on line 55
I’ve experimented with several combinations of settings, and no matter what I do I cannot get a modified or newly created feed to display.
