Should note that when I deactive GCal Events, the slideshow works just fine. When the GCal Events plugin is not, the console logs this error and the slideshow doesn’t work:
Uncaught TypeError: undefined is not a function (jquery.min.js?ver=1.5.1:16)
Having same problem – can be seen at http://www.stmarysonthehill.org – if you could fix this issue that would be great. It was working before I upgraded to WP 4.1 and GCal Events to whatever the latest version is that works with the new Google Calendar stuff.
