Add to cart button not working on single product pages

Here’s the dilemma.

ON a single product page(https://manflowyoga.com/product/man-flow-diet/) clicking the add to cart button does nothing but redirect you to the (still empty) cart.

if you are on the category archive page(https://manflowyoga.com/product-category/ebooks/) and click on the “add to cart” button that appears when you hover over a product, it adds it to the cart. and any subsequent product you try to add from a single product page now works, even if you empty the cart.

I don’t know what’s going on or how to fix it.
