Hi,

Recently I noticed that on my Debian box newly upgraded to 13 (trixie),
tending to moderation tasks no longer worked.

This was due to django.contrib.humanize missing from the INSTALLED_APPS
in /etc/mailman3/mailman-web.py , which is initialized from
/usr/share/mailman3-web/settings_local.py.sample

Thanks,

Alain
