After enabling "mod_ssl" and adding my first VirtualHost for port 443 I was puzzled to learn that
apachectl status no longer works even though "mod_status" was working before. Apache is however running fine and serving all requests.
Finally I realized that I did not enable the "default-ssl" site. So after enabling it and doing a
apachectl graceful issuing
apachectl status started to provide the exptected information again.
