I have Woocommerce composite plugin installed in my site.
The quantity button and add to cart buttons are hidden from the front end but I can see them getting executed through Firebug.
After clicking on add-to-cart button, it gives me the following error:
The configuration you have selected cannot be added to the cart. The quantity of "Vin #1" must be between 1 and 1.
How to solve this?
