If the online store does not have its own SSL certificate, then it will have to share our SSL site. In this case, the design from the web site must be mirrored to our secure site. Generally this is done during the initial configuration of the site. If the design, navigation menu, or other links have changed since the design integration was initially done, it will need to be performed again.
To update your design integration to the SSL site, do the following:
Login to control panel.
Click Online Store.
Go to the Store Design Settings.
Click to Get Header/Footer HTML.
Now you will see the updated HTML code for your site.
Click Next.
Click Save Settings.
This should update your site to show the most recent design settings from your website.
