If the padlock icon isn’t appearing on your site after the SSL certificate has been installed, there could be a coding issue in the <head> section of your page(s).
To troubleshoot, first check your HTML for the following code between your <head> tags:
This code forces all relative links to revert to “http” rather than stay on “https”. As a result, the SSL session cannot be set up and the padlock cannot appear.
To fix the issue, REMOVE the code <BASE href=”http://www.domain.com”> from the web page.
Also ensure there are no further references to http:// elsewhere in the affected pages’ code.
