Hi James,
Thanks for responding and I appreciate your explanation. While hoping to receive a response, I backed up my site and reinstalled the Dara theme. After re-adding the header graphic, background image, and re-publishing the site, Google Chrome indicated that the site was fully secure by displaying the locked padlock icon. I noticed that the SVG container declaration still shows “https://” but Google Chrome is not flagging it as error.
Again, thanks for responding. Have a great day, be safe and remain healthy.
