Comment:

 @hopetommola Can you tell me a bit more about your setup?

 * Is the site url saved in the database using an HTTPS scheme (e.g.
 `get_option('siteurl')`)?
 * Do you have any constants set for `WP_SITEURL`?
 * What is the value of `baseurl` coming from `wp_upload_dir()`?

 It's possible for your site url to be outputting an HTTP scheme and still
 have image `src` attributes showing as HTTPS when viewing the site over
 HTTPS depending on whether `wp_upload_dir()` is outputting an HTTP scheme
 instead of HTTPS.
