My store has been running fine for a long time. I got a report from a customer just now that she was trying to order something and it wouldn't process so I went to test the site and it no longer lists any products unless they are a "featured product." It shows that there are products in the categories but when you go to that category, there is nothing in it.
Any thought on what might've caused this. I haven't done anything that would cause it to change.
