I have a client who wants to use Shopp because it seems to be the only cart plugin that supports the LinkPoint / FirstData gateway.
Of course in order to make this work, one needs to install SSL on the account and somehow make either the entire site or preferably just the checkout pages use https. Can anyone explain how they set this up? Do you have to change the URL in Settings > General and/or add lines to the htaccess file or functions.php?
Unfortunately the Shopp documentation is pretty thin, and searches of this forum and theirs have turned up a lot of questions but not much in the way of answers.
