I just purchased Sydney Pro in hopes of fixing a problem I was having in the free version of the Sydney theme. I still have the same problem. My site is secure, except for the main page. As soon as I change anything in the Header Area of the theme appearance, I get an insecure image warning. When using the default images with the theme, everything is secure. When I go into sitetitle/tagline/logo area and add a logo I receive an insecure images error. The same thing happens when I go into the Header Area, and then change the picture on the Header Slider. While using the default images, everything is secure. As soon as I change the slider picture, I receive an insecure image warning.
Can you please tell me how to fix this?
