When I first upgraded to version 2.6, an Editorial Control Window was available however, as in another post
"When I click 'Edit related posts' it brings up a window in the foreground with boxes that say "drag post here" but under "select other posts" there are no options."
I didn't understand what solution there was for this.
I've just checked it again today and now there is no editorial control window and no option to choose posts. It just doesn't show up.
Please advise as how to rectify this.
