Hi Luke,
I’m sorry that you’re running into this issue, but I’ll be happy to help you out.
Events Calendar Pro should be compatible with WooCommerce (this is one of the supported platforms for Event Tickets Plus), and so far, I have not been able to recreate this issue locally. Can you send me a screenshot of what you are seeing on your WooCommerce page?
Can you also try dropping down to a default environment with Twenty Seventeen enabled and all other plugins besides WooCommerce, The Events Calendar, and Events Calendar Pro disabled to see if you are still running into this issue then? If not, then try enabling your theme and each of the other plugins (one at a time) until the issue reappears. Make sure to have WP_DEBUG enabled during testing and copy/paste any errors that you see here.
Let me know what you find!
Thanks,
Jennifer
