DeviceChannelMapings.aspx prevents enabling Publishing in a new site


  • I inherited an environment in which Publishing is enabled everywhere, so creating a new site template is problematic. I have created a new template based on the Blank template and then partially configured the site (with publishing not yet enabled).  I successfully create a new site with that template, but in subsequent new sites Publishing cannot be enabled.

    "The URL '_catalogs/masterpage/_DeviceChannelMappings.aspx' is invalid. It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web.'

    Doesn't matter what I do with that file, which DOES exist in the site. Publishing cannot be enabled from the GUI. And what little I have found online has not addressed the problem.

    Any thoughts?
