thanks
i also did my best to edit the plugin php files manually.
i edited the file located in below address:
woocommerce-cart-stock-reducer/includes/class-woocommerce-cart-stock-reducer.php
in line 1005 of that file i changed the number 1 to 0.
so the add to cart button and stock Qty have shown again ?? !
but only the quantity field (that user choose the amount he wants to buy) is still not showing.
i’ll wait for your help.
thanks a lot
