Is there anyone running a ZenCart site hosted on Mac Lion Server and is able to use a security certificate? I am struggling and would love to get some help.

I have installed a certificate from RapidSSL on my server. If I apply the certificate to my website, and edit the configure files for "true" on use of https, the server wants to use https for the whole site, and not just the pages ZC chooses. This means that I go to a single product-site, the system tries to access a https page that does not excist since ZC does not apply ssl to single product-pages.

Can anyone give simple step-by-step instructions? Or a hint what I may be doing wrong?
