We are required to convert our site to https protocol. However, when ever we have a menu that contains sub-menu items we get the Mixed-content warning pop-up when the sub menu is displayed. We are unable to turn the warning off in the corporate IE 6, 7 image because they have disabled the security options.
Additionally, If you select NO on the mixed-content window you get a 404 on /context/faces/pagerror.gif and /context/faces/refresh.gif. These are not in our application.
