The mailing list for listmasters using Sympa

[Mark London <address@concealed>]

I just added a footer to my mailing list, that has the auto_signoff 
link.   But the link simply brings me to the home page.   The system log 
shows:

Jul 24 13:43:49 www wwsympa[18905]: info 
main::do_auto_signoff(address@concealed\
) [robot burningplasma.org] [session 00218728281202] [client 
198.125.178.132] [\
user address@concealed] [list test]
Jul 24 13:43:49 www wwsympa[18905]: notice 
Sympa::Scenario::is_purely_closed() \
Scenario /home/sympa/default/scenari/unsubscribe.closed is purely closed

What do I need to do to fix this?  Thanks. - Mark
