gii, CRUD, error : suffixed with "Controller"

I am not able to generate CRUD.

I am getting the error that "Controller class name must be suffixed with "Controller" ".

Although it is suffixed as "ControllerTproducta", i also tried to give full path: advanced\backend\controllers\ControllerTproducta.

Where i should search for a mistake?

Please find screenshot enclosed.

thanks!

Suffix means to add to the end of the word. for example: productController.

Thank you, works!
