I also asked this over on the general forums but thought it may be easier for someone on here to answer.
This issue is regarding the quantity. When a quantity is added to the cart, it auto directs to the cart contents (a woocommerce option I opted for) but upon getting to the cart contents, even though the correct product has been picked up, the qty field is blank. I thought it may just be a case of the quantity not displaying and tried just clicking 'go to checkout' but that tells me the cart is empty so it simply isn't passing the quantity through to the cart contents page. Instead user needs to enter qty and click 'add to cart' then they are directed to the cart contents, then they would need to add qty again and click 'continue to checkout'.
Can anyone of think of a reason why this would be?
