                dirs: [ ]
            }
        ]
    }

}

But in my app I receive answer empty: (my app runs in a tomcat server and i call url "http://localhost/elfinder/connectors/php/connector.php" to a apache server"...

I have 2 web servers Apache tomcat + apache xampp (to execute connector written in php)

Anybody knows something is really urgent... and i dont know what to do...
