Error: Missing Controller

Missing Controller 📋

Cake\Http\Exception\MissingControllerException

Error HowToRecpoController could not be found.

In the case you tried to access a plugin controller make sure you added it to your composer file or you use the autoload option for the plugin.

Suggestion Create the class HowToRecpoController below in file: src/Controller/HowToRecpoController.php

    <?php
    namespace App\Controller;

    use App\Controller\AppController;

    class HowToRecpoController extends AppController
    {

    }
