Error

Class 'App\Http\Controllers\Controller' not found http://localhost:8000/articles/2

I am not sure where I am going wrong. I have looked at the documentation for routes/controllers in Laravel 8, and it looks like what I have should be working.

Answer 1

It seems there is something wrong with your extended controller.

please check Controller.php existed in App\Http\Controllers or not.

All controller same as yours (ArticlesController) extended from Controller
