Running my own designed custom theme "mdbootstrap" designed by myself. Integrating WooCommerce 2.4.12. and upon testing there is an issue adding variable products to the cart. Basically the add to cart button is hidden and doesn't appear once a variant is selected .
If I switch to the TwentyEleven theme, the issue resolves itself.
I can force button to show by adding to css
.single_variation_wrap{display:block !important;}
but even then when I submit "Add to card" page is reloading and when I move to cart page I am getting error: Please choose product options…

Normal products works like a charm: http://mdb.nomadflow.com/product/blog-homepage-template/
