Good evening Schalk!
Thank you for reaching out to us.
I would love to help you with this topic.
By the symptoms you are describing, I am pretty sure that there is some type of conflict at play.
Either with your WordPress theme itself, or with some of the the Events Calendar customizations you have made in the past. These probably need updating.
There are 2 tests worth trying while a maintenance page plugin is up and after you have made a database backup. You will also need to restore the latest version of /wp-content/plugins/event-tickets/src/views/tickets/email.php:
- If there is a /tribe-events/ folder in your theme, rename it temporarily to /z_tribe-events/
- Try temporarily reverting back to a default WordPress theme
Check if the issue persists while trying these.
Let me know how that goes.
Best regards,
Geoff B.
