I wanted to use the theme charcoal_grey for a HTML5 help output.
In Publish Settings, I clicked on Responsive HTML5, then under Manage Layout I clicked on "New" and choose Charcoal_Grey. I left all settings as they were to get a test output file first. But instead, it showed me a cryptic message in the log, that screen layouts are not in the settings file. ("In dieser Ausgabe verwendete Bildschirmlayouts sind nicht in der Einstellungsdatei enthalten.")
After a while I tried to check the Charcoal_Grey files in the installation directory, but there are none.
Why are those files not there? How can I use the Charcoal_Grey theme??
