Anyone ?

Hi, I`m creating new payment gateway module for older 1.4.9 prestashop version. I want to know how to show errors in backoffice modules, becouse, at this moment, when I turn on: //in config.inc.php @ini_set('display_errors', 'on'); define('_PS_DEBUG_SQL_', true); //in defines.inc.php define('_PS_MODE_DEV_', true); define('_PS_MODE_DEMO_', true); there is nothing to show in modules (look in attached picture)
