I'm not sure what I've done wrong here - both the widget and shortcode for "Upcoming Events" have stopped displaying anything except "No upcoming events". I've double checked that both the calendar and the (recurring) events are public, and I've checked the iCalendar URL is correct.
They both worked when I set them up originally, albeit with incorrect time zones, and I haven't touched them since, so I'm not sure there's much more detail I can give.
On http://notslangcath.wordpress.com/schedule/ you can see the Google styled embedded one works fine, but above it is an Upcoming Events shortcode drawing from the same calendar. It used to display a table of events, but now it just says "No upcoming events". The same text is shown in the widget at the side.
The calendar itself can be viewed at https://www.google.com/calendar/embed?src=0bf7degac4km43sb0g4ha63uuo%40group.calendar.google.com&ctz=America/Los_Angeles
Any advice welcomed.
