I installed Mailman 3 almost 2 years ago. I only now noticed that members of a mailing list can't view the list of members. Even moderators can't see the list. Only Owners. The error message is "You do not have permissions to visit this page."

Mailman Core Version GNU Mailman 3.3.8 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] Postorius Version 1.3.8

Any ideas? I did make a few "minor" changes to the code, but hopefully it didn't cause this problem. What file(s) contains the code that checks for permissions? Or maybe there is a config file?

I also notice by default, for all users, in their "Global Mailman Preferences", the default setting for "Hide Address" is "Yes". How can I change that to be "No". And can I reset that setting for all my present users? Thanks. - Mark
