I got live site here
http://www.hip-monkey.com/t-shirtsits using 2.0.18a.
Here is what we did, we use the child products for the shirt sizes and colors see example here:
http://www.hip-monkey.com/t-shirts/dj-yoda-detailNow its showing the stock on the front page and we just sold Size M, Black so the stock should be 0 not 1...
in the shop front I have selected "Do not Display Product, if child products also out of stock"
Further more if I try to buy 3 of the product that there is only "1" it says....
"Continue Shopping
Product out of stock
DJ Yoda-M-black was added to your cart"
the 2 first sentences make sense, but the last one says that its added to my cart... (btw it isn't, which is good).
Any ideas, I believe its a bug as Im pretty sure I have set up everything correctly
