Why does the free shared SSL have browser warnings?
If you use the free shared SSL, the browser will show a warning page instead of your site. The reason for this is that the shared SSL is not made specifically for your domain, therefore the security certificate does not match your domain.
How to avoid the browser warning:
If you want to completely get rid of the warning message, the only solution is to purchase a private SSL certificate. We sell them as a product add-on to your hosting account.
