The buttons on our site are no longer working

Hi there, I need your help. 

Buttons on our site no longer work, the customer can't add items to the cart.  We have a Brooklyn theme version 8.0.0

BITE HELPER® - Itch Neutralizer | Official Store by Maxogen – Bite Helper

Thanks in advance

It looks like there is a javascript error. When I click the button it is outputting:
"POST https://www.bitehelper.com/cart/add.js 404

Might help to see the customizer/settings. Could a link to a product have changed? It seems like this would have been a custom feature added to your theme? I have not worked with this theme in a while but usually order now buttons have some special functionality.
