Per the discussion at Wikidata_talk:Edit_groups#Not_working? it seems like there's an issue with edit gruops. I understand you are currently too busy to deal with it. Is this something someone else could look into? Maybe if you gave them access to the toolforge project? Or do you have a sense for how long it will be broken?
