Hi Dan,
I am using content_type__create_type that is where RI Triggers are right? Deleting the content type and calling it again after your fix should be fine right?
I am also inheriting from content_item. Since that was the default, I should change that to content_revision. I thought the code was more updated than that diagram.
DonB,
File-storage fs_root_folders does inherit from cr_revisions. Which I must do too.
