[Mailman-Users] Bug reported when creating a new list from webpage

[Mark Dale]

That's great Mark, many thanks.

Just recapping for anyone else's interest.
------------------------------------------------------------------

After installing Mailman, when first attemping to create a new list
using the webpage - it returned a "You don't have permission".

(Creating a new list from the terminal was working okay)

This was fixed by running: sudo mmsitepass -c myNewPassword
and restarting: sudo /etc/init.d/mailman restart

Then, when trying to create a new list from the webpage, it returned an
error "Bug in Mailman ..."

This was fixed by settig correct permissions and group/owner on the
files as Mark explained.


% /var/lib/mailman/data: ll
total 76
drwxrwsr-x 2 root     list  4096 Jul  1 06:19 .
