Firefox is stating “Loading mixed (insecure) display content “https://demo.athemes.com/atu-agency/wp-content/uploads/sites/86/2018/06/books-business-computer-459654.jpg” on a secure page”
So I have installed Better Search Replace and tried HTTP to https but this file still is directed to your site. First, I don’t even see how to access or change this image, I assume that it is the one at the top of the page. I’m okay leaving it as I like it but knowing where it is and how to access it would be nice and how to I redirect this image to my site?
