It is definitely related to he secure url setting for your store. You should be able to access anything in the backoffice of your store with both a secure url and a non-secure url. If the secure url does not allow you to get to the location of the html editor configuration files then it can't be loaded so it won't work. So contact your host and make sure that the secure urls you have configured allow access to all areas of the store including the html directory, images, cgis etc.
