Hi,

Please post log file  for analysis.

Messages are not dedicated to users any more on V9, as they would be displayed on today screen which is not the first page any more (since many versions).
So we focused on messages on Login page (for everyone) and Legal Messages on bottom of page.
To send a message to single user, user alerts through admin screen.

Hi, 
Sade 🙁
I understand but :
- How do i send specific messages to a profil or a role  (team members , project managers) ?
- Why the area "Messages" is still displayed on the today's page ?
- And so, what are "messages" used for ?

Thank you

- How do i send specific messages to a profil or a role  (team members , project managers) ?

There is no replacement for this feature on V9.0.
We just observed that messages on Today page were just never read.
So we'll think of enhancement for Legal Notice, that are displayed on bottom of page and "block" the screen to force reading
of extension of notification system.

- Why the area "Messages" is still displayed on the today's page ?

It's only visible with the "old interface"

- And so, what are "messages" used for ?

On V9 it is dedicated to information that appears on Login Screen

I think I got a clue.
If using old interface, or up to V8.6.6, there is a fix that may help :
add 3 lines adfter line 310 in model/Security.php

          $check=Security::checkDisplayMenuForUser(substr($menuName,4),false);
          if (!$check and $menuName=='menuAffectable') $check=Security::checkDisplayMenuForUser('User',false);
          if (!$check and $menuName=='menuAffectable') $check=Security::checkDisplayMenuForUser('Resource',false);
          if (!$check and $menuName=='menuAffectable') $check=Security::checkDisplayMenuForUser('Contact',false);

Hope this helps

Ok with the 3 lines. It works and no more issue when i select a user(or a profil) for a message. 
But this "new" message from login page doesn't interest me anymore.

Happy new year to everyone !
