How to use the free shared SSL?In order to use the server's shared SSL please configure your scripts by this address:
https://servername.com/~username
* You can find your server name by logging in your Customer's area and going to My account -> Manage (next to your account). Your server name is contained in the name servers for your domain. For example, ns1.siteground123.com - your server name is siteground123.com;
* Your username is your Cpanel's username.
Please bear in mind that the shared SSL will always show a popup warning. For more information check this link.
