[MM3-users] Re: (venv) mailman-web migrate (as explained) fails with "django.core.exceptions.ImproperlyConfigured: allauth.account.middleware.AccountMiddleware must be added to settings.MIDDLEWARE"

Confirmed.

pip install --upgrade django-allauth

solved that issue.

Now I set up "mailman-web createsuperuser" and confirmed my e-mail etc. and I am logged in as admin.

However myserver/mailman3 page is throwing

Erfolgreich als Admin angemeldet. Something went wrong

...

...

HTTP Error 401: REST API authorization failed

Even when the API keys are unchanged from my previous installation. Any idea what can be wrong here?
