Greetings. Many thanks to Joe for figuring this out. The missing piece was to add the following to the ssl-global.conf file; <VirtualHost *:443> DocumentRoot "/srv/www/htdocs" SSLEngine on </VirtualHost> This was added near the top of the file, just after the 'IFModule' and 'IFDefine' in the file. Again, many thanks, Joe. Regards, Steve
