I’m still having issues with another site: https://www.swflsustainability.com/events/. The page goes to a 404 now. I went through the same process and removed the files via ftp, then downloaded a fresh install of the event plugin… help!?!
I applied the snippet to the child theme functions file, verified file is loading, reactivated YOAST and tickets no longer get saved with or without woocommerce. So the fix did not work for me or do I need to add it somewhere else?
