MarketPress Add To Cart Does Not Work

Hello,

In store settings when Checkout Button Type is set to Add To Cart, clicking it does not add the item to the cart.

The cart will never populate with anything while setting is Add To Cart.

However, when the setting is Buy Now, then clicking the Buy Now Button places the item in the cart and additional items can be added to the cart before proceeding to checkout.

Also, Empty Cart Button Does not work and can only remove items from cart by checking the remove checkbox beside the items in the cart and then clicking the update cart button.

Any suggestions would be appreciated.

Thanks,
