Force SSL on Coming Soon Page
Sometimes, even when you have a valid SSL certificate, people may still land on the insecure version. By enabling this option, you can redirect people to the secure version (https) of your coming soon page. The redirection only works for the coming soon page; not for the entire site and not for the preview.
DO NOT enable this option unless you have a valid SSL certificate installed. Check if you do by opening your site via the HTTPS protocol - https://www.site.com/
