Whenever an item is added to the cart (from the single product page), refreshing the page or going to the cart and using the browser's back button to return to the product page adds another of that item to the cart automatically. Is there a way to stop this from happening?
I suspect it has something to do with the "product successfully added to cart" message that appears (and stays when page is refreshed or you return back to the page). I'm using the free mystile theme. I would share the link to the site, but we have an under construction page up.
Thanks for your help.
