Good evening Mark and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
Unfortunately, it seems you have removed that link from your live calendar.
If you could leave it in place, that would help me troubleshoot.
Could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
Hang in there!
Geoff B.
