Urgent stuck in loop for add to cart

[Arun_O]

Hey my website url is rootshandloom.com but recently something seems to have happened and none of my customers are able to check out. 

clicking the add to cart button gets them stuck in a loop and it doesnt add the item to the cart.

Would appreciate any help. 

Using craft theme by shopify. Checking console shows me an error when i click add to cart but not sure how do i fix it
