I have tried route:clear and route:cache

Hello @carlx1101

Welcome on this forum :)

I have 2 questions.

1: Does the create method exist in your controller and how does it looks like?

2: Can you place the code in your message and not a link to an image site with a lot of advertisements?

Hi, sorry for creating the inconvenient

1. this is my create method public function create() { return view('school.course.create'); }

I check all the details, everything is correct and working except the create() method not working for some reason

What happen if you change the method to?:

public function create() {
        return 'test';
}

If you get the test as return it means the controller is working. It can that your view does not exist on the correct way.
