After installing and enabling the commerce stock module, it seems impossible to add a product to the cart from the product detail page as shown below :
This is for both products in stock as out of stock.
Also the add to cart button is not shown with the 'out of stock' replacement label this module provides.
The wishlist is showing it correctly though :
Also in the product grid displays the add to cart widgets are disabled correctly
Is theme customization around this specific add to cart widget responsible for this malfunctioning ?
