Hello,
I find the solution !
It's a bug with the option "See warning messages on the GUI".
Steps :
- Remember to create a new user and a new profile (you can duplicate the sadmin profile in sadmin2)
For security, do not modify the default sadmin profile!!!!
- Then modify the sadmin2 profile and uncheck the "See warning messages on the GUI" option.
- Then assign your user to the sadmin2 profile.
Enjoy ;)
