I have installed the Laravel Collective HTML to do the forms and everything that makes Laravel safe.
I have the Collective\Html\HtmlServiceProvider::class, in the config / app.php in the providers section and I also have the
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
in the aliases section
Verify that you installed the correct version of the laravel collective package, you can see it in your composer.json
"laravelcollective/html":"^5.3.0"
In the app.php file, I see you've put it like this:
'Form' => Collective\Html\FormFacade::class
While in your title it says that you can not access with FORM, since you put Form, verify it, that may be the problem
