After clicking the register button for any of the events on my website an error pop up appears. It doesn’t actually stop the registration process but not something I want my clients to see. I have updated the plugin and flushed my sites cache but the error message still appears. How do I make this go away?
What you could do is configure you caching plugin (or contact your host) and ask them to exclude caching any pages with /events/ in the URL. If those pages are served from a cache, then that could cause other problems, like allow registration for an event that’s recently closed for registration.
