Same issue here – has stopped working in past 2 days and just showing the loading icon
I can’t think of anything I’ve done recently that would have caused it. Have you recently updated the plugin or your WordPress implementation?
Not recently so I don’t think it’s anything we’ve done – more likely something that’s changed in the way it feeds in.
Just tried installing a different plugin to do the same job and it’s also having the same problem – see thread:
Google Calendar Events
I’ve also posted on here as I think it’s definitely a Google issue!

There is another thread about this problem. I have a fix in a branch that you can try while I prepare it for going live.

The plugin has been updated to version 1.4.0 which has been upgraded to using Calendar API V3. Please update and follow the upgrade instructions. I am going to close this topic as resolved, but if you have any other issues, please open a new one.
