nothing display... ???

on my previous local database (on V11.1.2) it's works... but on the actual database (V11.1.3) it does not work

Check for errors in log file.
Possibly you have to setup or change $paramDbCollation in parameters.php

when I'am on Global planning view and I click on "show Actions" box, look the log files:

This is exactly what I wrote before.
set or chage parameter in parameters.php file to 

$paramDbCollation='utf8mb4_general_ci';

how can I modify this parameter, if the database is hosted by you?

in parameters.php file

Ok, in parameters.php file.
But how I can access it if the database is in ProjeQtor location ? database is not in our local server.

Hello,
We changed it for you. It should work fine, now.
Maybe you sent us your own files which where created long ago (before the utf8mb4 was used for the db).

it's work fine !
