You are having an issue with the loading the DTH News feed within the control panel. If it's even still happening, just ignore it. There's nothing on that control panel that you can't get to with a submenu. That news feed loads just fine is a SSL admin area. It was probably just a fluke, but even if not, it's nothing to worry about.
