Debug Toolbar Error karena Behavior

saya ingin semua halaman kecuali login page hanya bisa diakses user yang sudah login. Lalu saya tambahkan behavior access control ke configuration. Tapi stelah reload page, debug toolbar hanya blank putih/abu-abu.

$config = [

    'id' => 'basic',

    'basePath' => dirname(__DIR__),

    'bootstrap' => ['log'],

    'components' => [

        .....

    ],

    'params' => $params,

    'as AccessControl' => [

        'class' => \yii\filters\AccessControl::className(),

        'rules' => [

            [

                'allow' => true,

                'actions' => ['login', 'error'],

                'roles' => ['?'],

            ],

            [

                'allow' => false,

                'actions' => ['login'],

                'roles' => ['@'],

            ],

            [

                'allow' => true,

                'roles' => ['@'],

            ],

        ],

    ],

];
