Postorius is not working (throws "Error 500" suddenly after changing POSTORIUS_TEMPLATE_BASE_URL and changing back)

After having changed and re-changed "only" the line in /etc/mailman3/mailman-web.py (which looks to be only a "blinder" and the real problem could be a different one) POSTORIUS_TEMPLATE_BASE_URL = 'http://localhost/mailman3/' the web access via Postorius is not working any more and throws "Error 500" My logfile /var/log/mailman3/web/mailman-web.log shows now File "/usr/share/mailman3-web/manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/usr/local/lib/python3.9/dist-packages/django/core/management/__init__.py", line 446, in execute_from_command_line utility.execute() File "/usr/local/lib/python3.9/dist-packages/django/core/management/__init__.py", line 420, in execute django.setup() File "/usr/local/lib/python3.9/dist-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "/usr/local/lib/python3.9/dist-packages/django/apps/registry.py", line 116, in populate app_config.import_models() File "/usr/local/lib/python3.9/dist-packages/django/apps/config.py", line 269, in import_models self.models_module = import_module(models_module_name) File "/usr/lib/python3.9/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1030, in _gcd_import File "<frozen importlib._bootstrap>", line 1007, in _find_and_load File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 680, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 790, in exec_module File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed File "/usr/lib/python3/dist-packages/django_q/models.py", line 12, in <module> from django_q.signing import SignedPackage File "/usr/lib/python3/dist-packages/django_q/signing.py", line 7, in <module> from django_q import core_signing as signing File "/usr/lib/python3/dist-packages/django_q/core_signing.py", line 9, in <module> from django.utils.encoding import force_bytes, force_str, force_text ImportError: cannot import name 'force_text' from 'django.utils.encoding' (/usr/local/lib/python3.9/dist-packages/django/utils/encoding.py) I already run pip install -U postorius to update that (looks okay to me): Requirement already satisfied: postorius in /usr/local/lib/python3.9/dist-packages (1.3.8) Collecting postorius Using cached postorius-1.3.8-py3-none-any.whl Downloading postorius-1.3.7.tar.gz (3.2 MB) Requirement already satisfied: django-mailman3>=1.3.8 in /usr/local/lib/python3.9/dist-packages (from postorius) (1.3.9) Requirement already satisfied: readme-renderer[md] in /usr/lib/python3/dist-packages (from postorius) (24.0) Requirement already satisfied: django<4.2,>=3.2 in /usr/local/lib/python3.9/dist-packages (from postorius) (4.1.9) Requirement already satisfied: mailmanclient>=3.3.3 in /usr/local/lib/python3.9/dist-packages (from postorius) (3.3.5) Requirement already satisfied: sqlparse>=0.2.2 in /usr/lib/python3/dist-packages (from django<4.2,>=3.2->postorius) (0.4.1) Requirement already satisfied: asgiref<4,>=3.5.2 in /usr/local/lib/python3.9/dist-packages (from django<4.2,>=3.2->postorius) (3.7.2) Requirement already satisfied: typing-extensions>=4 in /usr/local/lib/python3.9/dist-packages (from asgiref<4,>=3.5.2->django<4.2,>=3.2->postorius) (4.6.3) Requirement already satisfied: django-allauth in /usr/lib/python3/dist-packages (from django-mailman3>=1.3.8->postorius) (0.44.0) Requirement already satisfied: pytz in /usr/lib/python3/dist-packages (from django-mailman3>=1.3.8->postorius) (2021.1) Requirement already satisfied: django-gravatar2>=1.0.6 in /usr/lib/python3/dist-packages (from django-mailman3>=1.3.8->postorius) (1.4.4) Requirement already satisfied: requests in /usr/lib/python3/dist-packages (from mailmanclient>=3.3.3->postorius) (2.25.1) Requirement already satisfied: cmarkgfm>=0.2.0 in /usr/lib/python3/dist-packages (from readme-renderer[md]->postorius) (0.4.2) dpkg -l | grep django ii python3-django 2:2.2.28-1~deb11u2 all High-level Python web development framework ii python3-django-allauth 0.44.0+ds-1+deb11u1 all Django app for local and social authentication (Python 3 version) ii python3-django-appconf 1.0.3-1 all helper class handling configuration defaults of apps -
