I checked with my host and it seems that having digital downloads on my host while using Zen Cart is a no-no.. They offer Zen Cart as a server install but don't permit digital product downloads with Zen Cart because of the redirect issue and htaccess issue. If you have a host like this - good luck using Zen Cart... They suggested several other cart systems - most everything but Zen Cart. What do I do with the week and a half I spent setting up Zen Cart? Sh☺σö£.. I wish there was a list of hosts not to use with Zen Cart - and a list of host that can use Zen Cart.
