I am trying to parse a feed from the Event Calendar Pro with amr ical feed list, but it's producing an error:
Fatal error: Call to a member function format() on a non-object in /home/icalevents/www/test/wp-content/plugins/amr-ical-events-list/includes/amr-import-ical.php on line 1072
I did a test on your test site under 'PScoggan Test' and am getting the same response.
Any thoughts? The first thing that comes to mind is the url to the file doesn't end in .ics?
On my test server I am using a new install of 3.9.1 with Twenty Fourteen them and no other plugins.
