Why is the controller not in yy2?

Question

Yii

Good afternoon. Faced the following problem:
yii2 advanced, created crud using gii, but I can not call the controller, although it is in place in the
Unknown Class folder - yii\base\UnknownClassException
Unable to find 'frontend\controllers\ResponsController'
In the config is 'controllerNamespace' = > '\frontend\controllers'.
What could it be?
PS in basic, Gii works with a bang

Answer 1

Maybe a response error - response? You open the respons/index route and the controller ResponseController.

Answer 2

No, everything turned out to be actually in different namespaces. It was weird to use them.
