sorry this is a bit weird. with this settings I still get the "This certificate was signed by an unknown authority" warning.

If I edit /etc/apache2/sites-enabled/100-premaman.co.za.vhost and add the line:

SSLCertificateChainFile /usr/local/ispconfig/interface/ssl/startssl.sub.class2.server.ca.crt

instead the warning is gone!?
