Hi James!
Thanks for getting in touch with us!
Let me help you with the troubleshooting.
First, please make sure you are using the latest versions of our plugins and see if any changes. Remember you can always download our plugins from your downloads page > https://theeventscalendar.com/my-account/downloads/
I can see events showing up for 2019 in your site. Were you able to solve the issue or are those different events?
If you still experience the problem, please share with us, in a private reply if you’d like, the URL for the gCal you are trying to import events from. We’ll run some tests on our end and see what we can find.
Thanks,
Victor
