The problem is only with Chrome (at least with the 48.0.2564.116 m version). We have "secure" content (SSL with particular certificate), and with Edge and Firefox after accept the risks and adding a exception, the page to edit shows perfect, with the styles, but don't with chrome, there the only one problem is that doesn't load the styles...
Any way, i dont know if the problem is because a fault in the configuration because in with edge and firefox works perfectly... Anyone more with this issue and any help?
