Bug: User Signup not working

[MarcoWel]

karrio 2026.1.21:

When ALLOW_SIGNUP env variable is not set explicitly, user signup does not work, even when enabled in platform console:

ALLOW_SIGNUP should default to true according to docs:
https://www.karrio.io/docs/platform/guides/feature-flags#allow-signup

Only when explicitly stating ALLOW_SIGNUP=true, the user can sign-up via portal or be added by admin.

Now even then, the user is not showing up under Staff & Permissions and cannot login.
Where can the admin approve new users?

[MarcoWel]

The new user is showing up in the Django backend:

After manually setting Active = true there, the user can login and then also shows up in the Staff & Permissions panel.
