The editorial control feature is cool! I like the idea of being able to pick and choose posts, however, it seems that this is not currently working properly on my plugin for my site.
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 did patch this plugin according to these directions https://wordpress.org/support/topic/related-post-criteria
I removed the lines that brought in anything besides tags. Is this why it isn't working?
