Hello,
I noticed a problem where the products were not added to my cart. I figured the problem was because I enabled Ajax through my add to cart button in the single product builder.
I followed the instructions here however the problem still persists.

I disabled Ajax in the Single Product Builder and deleted the code in the discussed file, however adding the product to cart is still broken.
