1) Please Check the file .
2) There is no error in the browser's console, just warning
"Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/ ."

3) No response in the file jsonPlanning.php just :
{
identifier: "id",
items: [ ]
}

N.B : i changed the path of my server ( confidentiality purpose ) 🙂

=> You have a configuration issue with SMTP server : emails are not sent

=> You're facing max_input_vars issue on "real work allocation" screen : increase this value in php.ini

=> There is an error about checklist access, to some element where type is not set. Do you remember how (on with element) you got this error ?

=> There is not error about planning :
1) can you try and go to the project (through projects screen) and just save the project (without any change) : what is result ? what is displayed on history for this change ?
2) add on debugLog line in /tool/jsonPlanning.php like this :

  $result=Sql::query($query);
debugLog($query);
  $nbRows=0;

then test again, check log file and post result here.
Thanks.

Regards.

Yeah,
but i can't edit the php.ini because we have a shared hosting ( Hostgator ) ( http://support.hostgator.com/articles/cpanel/php-settings-that-cannot-be-changed )

this is the log file after we add the code in 2)
