Woocommerce variable product add to cart issue.

I set up a store a couple of months ago, and the variable product drop down menu works there: Quattro Uomo

Now I am working on another store for my friend, using the same theme Snaps, but the drop down won’t work Enchanted

I have followed all instructions I could find on this forum, or in other places, that Google found for me. So far nothing worked. I have disabled and put back on all plugins, that I installed, but that didn’t change anything either.

Thanks everybody in advance!
