$_SERVER['HTTPS'] does exist on some servers. If for some reason your server doesn't provide $_SERVER['HTTPS'] and especially if you run on a different port (as the second condition also fails), you can always set $ScriptUrl and $PubDirUrl in config.php. I'll review the documentation to see if it is reliable to only use $_SERVER['HTTP_HTTPS'] as a check if the other 2 conditions do fail. --Petko May 04, 2018, at 09:41 AM
