Problema nel ErrorHandler.php file sul 85 line:

$result = Yii::$app->runAction($this->errorAction); 

Quando ErrorHandler prova eseguire ErrorAction, NotFoundHttpException attivato nuovamente e ErrorHandler mostra solo il messaggio di errore senza rendering.

Soluzione:

public function beforeAction($action) 
{ 
    if(!$action instanceof \yii\web\ErrorAction) { 
     throw new \yii\web\NotFoundHttpException('The requested page does not exist.'); 
    } 

    return parent::beforeAction($action); 
}
