Controller class could not be found

Hi,

I have problem in my application using CakePHP 2.2.5:

2014-07-21 16:35:53 Error: [MissingControllerException] Controller class ImgController could not be found.
#0 /app/webroot/index.php(92): Dispatcher->dispatch(Object(CakeRequest), Object(CakeResponse))

2014-07-21 16:48:20 Error: [MissingControllerException] Controller class Robots.txtController could not be found.
#0 /app/webroot/index.php(92): Dispatcher->dispatch(Object(CakeRequest), Object(CakeResponse))

Any ideas ?
