Registered user can't create a new topic, asked for registration again

Hi everybody !

I have a fresh installed Foswiki 1.1.5 and I have difficulties to allow a user to create a topic in a web.

This user is registered on my Foswiki and is a member of the group TestGroup I created.

I created a web with the following permissions (in the WebPreferences page of the web) :

Set DENYWEBVIEW = WikiGuest
Set ALLOWWEBVIEW = TestGroup
Set DENYWEBCHANGE = WikiGuest
Set ALLOWWEBCHANGE = AdminUser, TestGroup
Set DENYWEBRENAME = WikiGuest
Set ALLOWWEBRENAME = AdminUser, TestGroup
Set ALLOWTOPICCHANGE = AdminUser
Set ALLOWTOPICRENAME = AdminUser

Guests can't see the web but my user can. The problem is my user can't create a new topic in the web despite being member of the TestGroup...

When the user tries to create a new topic in this web, he is asked to register (redirected to foswiki/bin/manage/Myweb/ despite being already registered and logged in).

I can't find what I have done wrong... The user is also present in the htpasswd file.

I'm using Foswiki on Apache2 with mod_perl

EDIT 1 : It now works. I had to modify LocalSite.cfg to set the lines $Foswiki::cfg{SMTP}{MAILHOST} and $Foswiki::cfg{WebMasterEmail}

EDIT 2 : I was wrong with the previous edit. I installed Foswiki on production server and registered (and logged in) users are still asked for registration when they want to create a new page.

*EDIT 3

Now, when I try to change permissions on MyWeb I got the following error message : La valeur fournie pour action_save or action_cancel a été refusée ( = provided value for action_save or action_cancel was refused)

*EDIT 4

I applied the patch from Item11798, now I'm back to my previous problem

*EDIT 5

The only way users can create or edit a page for the moment is by authenticating as the administrator with bin/configure... which is bad. Any idea ?

Sorry for the bother.
