My wife has a product that we want to sell on the Internet as an ebook. The thing we don't know how to do is set up the download function so it can only be downloaded once after a purchase has been made. I'd appreciate any help you can provide. Thanks
You need to provide a link to the root location in your hosting account where your product is situated or else use a special server for that purpose. Many sites use a special server for this purpose integrated with suitable scripts.
