Good evening Jason and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the issues you have experienced while transitioning to Event Tickets Plus. Yikes!
I would love to help you with this topic.
In case you did not already read it, the following guide really helps ensure a smooth transition: https://theeventscalendar.com/knowledgebase/moving-to-event-tickets-plus/
With that in mind, from what I can gather, there could be a couple of explanations for this:
- You still have your WooCommerce tickets plugin active (as you can see in the guide, you will only need Event Tickets Plus active for this to work).
- There might be some customizations in your WordPress theme that require either updating or temporary removal (until you can update them). Try temporarily reverting back to a default WordPress theme such as twenty-sixteen to see if the issue persists.
Let me know how that goes.
Best regards,
Geoff B.
