Profile pictures don't persist after logoff/re-login
I'm having a problem with a jsConnect-configured Vanilla forum not persisting profile pictures after the user logs off.
I can successfully assign a profile picture, and it remains active until a logoff. Then it reverts to blank.
The forum is set to require a login in order to view posts, and it uses an external authentication/registration (exclusively) via jsConnect.
Any ideas as to why this might be happening?
