@katharina I believe you can extend ExceptionRenderer class with misstingController() method to handle missing controller errors in CakePHP, code:

<?php

// In src/Error/AppExceptionRenderer.php
namespace App\Error;

use Cake\Error\ExceptionRenderer;

class AppExceptionRenderer extends ExceptionRenderer
{
    public function missingController($error)
    {
        $response = $this->controller->response;

        return $response->withStringBody('Oops that controller is missing.');
    }
}

// In config/app.php
'Error' => [
    'exceptionRenderer' => 'App\Error\AppExceptionRenderer',
    // ...
],

There are different approaches to handle missing controller error in CakePHP. Here are a few ways:

  1. Check the controller name spelling: Make sure that the name of the controller is spelled correctly and that the file is located in the correct directory. If it is not, rename or move the controller file accordingly.
  2. Use routing: You can use the routing feature in CakePHP to redirect requests with a missing controller to a custom error page.


For example, in your routes.php file, you can add the following code:


Router::connect('/missing_controller', array('controller' => 'pages', 'action' => 'error'));


This will redirect any requests for missing controllers to the PagesController and the error action. You can customize the error message by editing the error.ctp file in the Pages view folder.

  1. Check the configuration: Make sure that the configuration values in the core.php and bootstrap.php files are correct. Check that the App folder location, url and other configurations values are correct.
  2. Use debugging: When the debug mode is set to 2 in the core.php file, CakePHP will display a detailed error message with information about the missing controller. This can help you identify the problem and fix it quickly.
  3. Check permissions: Make sure that the controller file and folder have the correct permissions set. Check that the web server user has permission to access the file.
