Good evening Melissa and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the missing export link.
I would love to help you with this topic.
Based on what I can see, it looks like you have some template customization at play.
Would you mind telling me if there is a /tribe-events/ folder in your WordPress theme’s directory?
Secondly, if you could do a quick test and temporarily revert back to a default WP theme such as twenty-fifteen and tell me if the button appears ?
Let me know how that goes.
Best regards,
Geoff B.
