Can't edit my plugin project page -- doesn't know it's me at .org

Pages on this site (.org) now have the .com banner, including my avatar, but it doesn't know it's really me when I try to edit my "Articulations and Ornamentation" page -- the three dots give me only "Revisions". Something is sorely amiss.

My browser address line right now says https://musescore.org/en/node/add/forum , but the .com banner is present.
