Woocommerce “add to cart” problem.

Hello.

I have a problem with WooCommerce.

On the product list page, button “add to cart” just does not add to cart.
Like there (https://radulovicdesign.rs.ba/kategorija-proizvoda/elektricne-gitare/)

When i open each product individually, then it’s working fine.
LIke there (https://radulovicdesign.rs.ba/proizvod/cort-aero11-2/)

Actually, the problem is about permalinks.

When i set it to “deaful” it works fine, but when i set it to “postname” it’s didn’t work.
Do you know how to make it work with “postname” settings?

Sorry for bad English.
