I have a website where is installed woocommerce theme and when i add a variable product i don't show add to cart button for that product. http://www.juzora.com/ is my website. For example if i visit the variable product like http://www.juzora.com/product/cowgirl-harem-pants/ I can't add this product to cart.
So... shouldn't you ask in a Woocommerce-forum? I fail to see how this is related to jQuery in any way...? There are no obvious jQuery-functions attached to the working Add to cart-buttons. So... how is this a jQuery-question?
