[MM3-users] Re: After server upgrade debian 11→12 and reinstalling everything in (venv), I got this error when accessing → mailman3/lists

I have standard installation Tom Sawyer 3.3.10.

I setup

base_url: https://mydomain/mailman3/lists

in mailman.cfg and restarted mailman3.

The variable is however not replaced, otherwise than you said above, and now simply "$mailinglist_url" is printed unreplaced in the footer.

What did I wrong? Where exactly is base_url to be set, I searched for it but could not find a suited information in the mailman documentation.
