The mailing list for listmasters using Sympa

[simone dal maso <address@concealed>]

Hello,
I'm really sad to make all these questions... but some problems are
out of my knowledge.
When I'm browsing the archive of a mailing list, I have the "reply"
button, in italian is "rispondi".
Ok, when I click on it, I return to the mailing list home page where
there is all the name of the lists.
If I open the source html page, the "reply" appears one time on line 1029:

1029   <input class="MainMenuLinks" type="submit"
name="action_compose_mail" value="Rispondi" /><br

Ok... but now? How can I reply via web?
Instead if I try to send a new message it works great!
Thank you and have a nice weekend.
Ps: Sympa 6.1.23 with debian 8.
