it also gives the message

(the view can be a string or an array)
index in public

try {

    $config = include  __DIR__ . "/../app/config/config.php"; //подключение базы данных

    include  __DIR__ . "/../app/config/loader.php"; //пока не знаю зачем

    include  __DIR__ . "/../app/config/services.php"; //подключение файла настроек

    $application = new \Phalcon\Mvc\Application($di);

    echo $application->handle()->getContent();//комментирую эту строку убирается сообщение про services.php 

}  catch (\Exception $e) {
    echo $e->getMessage();
}
