I have had 2 customers in the past 24 hours that while looking on my site I get Facebook messages from them. The messages are either just "Browse" or "Buy Now" with pics of products they are looking at. When I respond to their messages the first customer replies the Buy Now button isn't working. The second customer replied that she didn't message me that she was just looking. What do I need to do?
Well, click on the Buy Now button and see if it works. If it does, there's nothing to be done unless they meant the checkout button. If it doesn't work, some debugging would be required to find out what's wrong.
