I'm using My Calendar plugin by Joe Dolson. Previously I had been able to filter events by region. I upgraded the plugin from v1.9 to v1.10.12 and it seems to have stopped working. Here is the short code on my page:
[my_calendar_locations show="form" type="saved" datatype="region"]
The form shows on my page but it no longer works. When you select a region, it returns a blank calendar.
This feature is important to my site, so for the time-being I have reverted the plugin to version 1.9. Any help would be appreciated.
