Hi,
Thanks for reaching out to us! I would be happy to help you 🙂
It seems there’s a conflict somewhere — at least, there are a couple of JavaScript errors in your website that may have unwanted effects.
Did you update your theme or a plugin recently? Did it use to work fine until recently? If you think the latest TEC update could have broken something, you can always roll back and reinstall the previous version.
That being said, I would definitely recommend you to do some testing for conflict. It would be ideal if you had a staging website to run those tests.
Cheers,
Jeremy
