Thanks but I did that as described. That is how it is currently set up. I took a look at this post.
I took a look at my vhosts_ispconfig.conf file and noticed I don't have a NameVirtualHost XXX.XXX.XXX.XXX:443 or VirtualHost XXX.XXX.XXX.XXX:443 even though I have the SSL box checked in the ISP Site Control Panel. I have restarted the web-server service since I checked this box. I tried to edit this file and add the appropriate information, but when I restart the service the changes are erased.
Thanks again for any help.
