Mailman not archiving

Hello,
We use Mailman official package.
Messages from Mailman lists should be monthly archived, but Mailman says that there is no archive since hundred posted messages for 6 months.
Is thas supposed to work ?
Thanks

Hello,
I have the same problem.
I looked a bit into documentation or logs yet but did not find much. If anyone can help, that would be great!

I found this on the mailman FAQ but we are not using Apache:

Q. I can't access the public archives. Why?
A. If you are using Apache, you must make sure that FollowSymLinks is enabled for the path to the public archives. Note that the actual archives always reside in the private tree, and only when archives are public, is the symlink followed. See this archive message for more details:
