Plugin not working for me

Hello,

I have followed the installation and setup instructions for the Eventbrite API plugin and I have a few live, public events in Eventbrite, but it isn’t working on my page. The page is https://www.patchoftheplanet.com/learn/

Please could someone give me a sense of what’s going wrong? I’m afraid I’m not hugely familiar with the coding CSS side of things, but happy to do anything if I can understand it!

Thanks in advance.
Neil
