To use the shared SSL Certificate, update the hyperlinks that need to be secure to use the base URL of https://secure.Gesatech.com/~yourunixusername.
The yourunixusername is the 8 character username of your Gesatech account as listed in the cPanel on the left side.
Alternatively, you may use a private SSL Certificate specifically created for your primary domain.
Note: The shared SSL Certificate can only be used if your account is on a shared IP address.
