Mixed Content: The page at 'https://mydomain.com' was loaded over HTTPS, but requested an insecure stylesheet
A view source reveals
This href value appears to be set in /libraries/joomla/document/renderer/html/head.php, which calls
to get this value. In /libraries/joomla/document/document.php, this value is set with an
$options array passed to the constructor, but I cannot find where these options are set.
I had thought this value, as well as the constants
JPATH_SITE, etc., would be assigned whichever protocol the site uses. Am I missing a setting somewhere on the back end of the site?
I am using Joomla 3.7.2
