Try renaming your controller to NewsesController.php and change the class name inside of the file to match the file.

class NewsesController extends BaseController {

Then in your route use:

Route::get ('news', 'NewsesController@index');

i have already tried this but no result

Check your app.php file in the /app/config directory. And set debug mode to true so we can see the actual error message.

First set your app in debug mode by going to config/app.php and change debug to true.

Now you will find what the error is
