What steps does it take to reproduce the issue?
- Log into https://demo.dataverse.org with Institutional Login (Shibboleth)
- Go to Account page.
- Click "Account Information" button
- Observe empty dropdown (screenshot below)
To whom does it occur (all users, curators, superusers)?
All users.
What did you expect to happen?
I'm pretty sure that previously the "Account Information" button shouldn't appear at all?
Which version of Dataverse are you using?
Dataverse 5.8 but I'm seeing the same on Dataverse 5.6.
