I am trying out ZenCart. I need to know how to update the number of items in stock. At first when browsing to a product on the site, I get a message that says the item is out of stock. I messed around in the admin page a bit, and now instead there is a button there that says "Contact Us."
Preferably I would like that button removed and add the ability to add item to cart instead, without checking if item is in stock, and without any warning regarding number of items in stock.
