Hey Greg,
Thank you for reaching out to us! I’m so sorry to hear that you are having problems with your shortcodes. Let me help you to solve this!
I’ve just accessed the link you shared and I see a series of js errors in the console (here’s a screenshot > https://ibb.co/jCagA6).
The first two errors are associated with The Events Calendar, but as you can see in the screenshot, they are coming from your cached content. So to get started, I would recommend you to purge your site’s cache and check if the problem is solved after that!
If the issue persists, please let me know and I’ll be happy to help you with the next steps.
Cheers!
Patricia
