Hi Rich,
Thanks for reaching out to us! I’d be happy to help you 🙂
When did you notice that problem? After a recent update of our plugins? If that’s the case, you may roll back to a previous version so that your end users could still sign up while we’ll fix this issue:Â https://theeventscalendar.com/knowledgebase/downgrading-plugin-past-version/
Also, could you share your System Information, so that I could understand your setup better?
Cheers,
Jeremy
