Whenever a customer is on the product page, they are not able to use the add to cart button, as well as the buy button adds a PayPal button that doesn’t work either. I use Flow theme 33.2.1 and have attached the website below:
Thank you for reaching out about this! I was not able to replicate the issue you are experiencing, so that does make it a bit harder to troubleshoot. I do have a few questions though that might help us narrow things down:
Do the carts that have this issue checking out have the same or similar items in them?
Does this issue happen on both the slide out cart and the cart page?
Have you tried disabling the slide out cart to see if that resolves the issue?
Let me know if those troubleshooting steps make a difference at all.
