"The Page Has Expired Due to inactivity" Error

I'm new with Laravel, I am now using the latest version 5.6. Despite the version difference on this video I was able to work my way up to the Form Builder part of the course. I was working on:

the create.blade.php file with this code:

@extends('layouts.main') @section('content') <form method="POST" action="http://laravel.test/todos" accept-charset="UTF-8"> <label for="title">List Title</label> <input name="title" type="text" id="title"> <input class="button" type="submit" value="submit"> </form>

@stop

and TodoListController.php code

public function create() { return View('todos.create'); }

public function store() 
{
    return "Creating a New List";
    //$list = new TodoList();
    //$list->name = "Another List";
    //$list->save();
}

However when I run the site I get a "The Page Has Expired Due to inactivity" Error.

Can anybody tell me what I'm doing wrong?

Thanks
