I have a site with several content types, all of which are OG content except one type, Group, which is a group.
I also have Panelizer and Panels Everywhere enabled. When I go to edit the default Panelizer settings for each content type, I have no problem doing so, except when the node type is Group. I can turn on Panelizer for Groups but then when I go to set the default settings for individual view modes, I get a "page not found" error.
I've cleared caches, rebuilt the registry, and even reinstalled Drupal, to no avail.
