Problem to put product in cart

Good morning.

I have a problem, when I try to add a product to the cart it does not add and it stays in the loading, and when I’m inside the product it adds normal, but it stays in the loading in the checkout and I can not finish. When I disable the plugin I can finish normally. I’m using wp rocket too. What can I do to get this right?
