Good afternoon Anna and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the stock issues you have been dealing with.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your system information in a private reply ? (following the instructions found in the link)
While you are at it, could you tell me if there is a /tribe-events folder located in your WordPress theme ?
Have a good week-end,
Geoff B.
