I can access my site with https upon login, and all appears fine until I am in Edit mode and and try to save any edits from within the Page Properties pop-up box. Then the browser throws a security warning such as in Safari: "Although the page is encrypted, the information is to be sent over an unencrypted connection", then the popup just sits and spins. More specifically Chrome developer console indicates: Unsafe JavaScript attempt to access frame with URL...https://... The frame requesting access has a protocol of 'https', the frame being accessed has a protocol of 'http'. Protocols must match.

seems to originate from: "/mysite/index.php/tools/required/edit_collection_popup.php?"
within <div id="ccm-edit-collection">
or possibly:
"/mysite/index.php/tools/required/page_controls_menu_js.php"
or specifically some iframe within: "/concrete/js/jquery.form.js"

Has anyone experienced this behavior in the Page Properties form?

How do I secure the resources which C5 is using in the Page Properties dialog pop-up box?
