Hi everyone, Mark thanks for the reply. My installation was done on Debian Buster by installing the mailman3-full package
I can't find the path you indicated:
Mailman core in mailman/messages/ Hyperkitty in hyperkitty/local/ django-mailman3 in django-mailman3/local/ postorius in postorius/local/ Maybe some packages are missing?
To set language for Django (i.e. hyperkitty and postorius) see https://docs.djangoproject.com/en/3.0/topics/i18n/translation/#how-django-di.... What are the files to be edited?
For Mailman core, set [mailman] default_language: in mailman.cfg. Ok Done
You also need to (re)generate the .mo file which can be done with the generate_mo.sh script. I can't find the script
For Django, you need to generate .mo files with django_admin compilemessages Where should this be written?
Thank you Max
