I'm trying to launch a store this week but ran into a BIG issue with the woocommerce plugin.
After inserting variations, the "Add to Cart" button disappears (http://imgur.com/XEkAZx7), but the button shows up without a problem when there are no variations (http://imgur.com/dEHf5jU). Disabling the stylesheet, the button still does not appear. The button does, however, exist in the source code, but "display:none;" is hard-coded (inline) and that attribute doesn't seem to toggle once a variation is selected. What could cause this?
