Did you at any point run the :latest version from docker before downgrading back to v0.4.24? That might explain it.

You can try fixing it by running this in archivebox shell:

from django.contrib.sessions.models import Session
Session.objects.all().delete()

You should also clear your browser cookies and cache for https://archivebox.saturn.local so that it doesn’t resend the bad token to the backend, then try logging in again.

This error appears to be specific to Django 3.0.6, and is fixed with 3.1 which we will release with the next ArchiveBox v0.5.0 version in a few weeks, so as long as we get it working for you I’m not too worried about it affecting other users.

Not at any time, but always, the image is automatically updated to the image on Docker Hub marked as latest

Cleaned cache and cookies and now it works, thanks
