Had to install an SSL in a domain managed by Plesk 8.3. Had suPHP running and had major problems with the shopping cart not transferring cart items between the http and https. I would take the shopping cart out of https and put it into http and all would be fine. Tracked it down to session ID and cookie issues. Domain is configured to run SSL out of the same directory, have a certificate and a dedicated IP for this domain. Ended up having to disable suPHP for this domain and go back to having all PHP files owned by Apache. Anyone had any experience with this? I have seen some posts about a vhost_ssl.conf but can't find a whole lot of information about it. Server is FC6 64-bit running MySQL 5.0.27 and PHP 5.1.6.
