All website assets must be loaded securely for the SSL lock icon to display.
For example, when linking to an image you must link to it using a relative URL like <img src="/image.jpg"> and not <img src="http://domain.com/image.jpg">.
Even one insecure link will cause the lock icon to not display and could result in your website loading incorrectly when accessed over HTTPS.
If the lock icon is not displaying, changes to your website code will be required to make your website compatible with HTTPS / SSL.
Varial Hosting does not provide any support for updating a customer’s website code for SSL compatibility. Please consult a web design firm if you require assistance with this.
