ImportError at/mailman3/lists/ Module "django.contrib.sessions.serializers" does not define a "PickleSerializer" attribute/class

Ok, I found a proper line in my settings.py and rebuilded the file settings.py completely from the one proposed here: https://docs.mailman3.org/en/latest/install/virtualenv.html

Issue is fixed now.
