I am upgrading from 4.2 directly to 5.1 and run into problems with the Html and Form classes.
I followed the upgrade notes, and did
I think I have found the solution.
In your app.php
you have declared
'Form' => Illuminate\Html\FormFacade::class,
'Html' => Illuminate\Html\HtmlFacade::class,
While in your View
you have called the same class as
{!! HTML::style('css/bootstrap.min.css') !!}
There is nothing wrong with the packages as the marked answer above but rather difference in capitalization of the word HTML
as the previous documentation ver 5.0.*.
It should be
'Form' => Illuminate\Html\FormFacade::class,
'HTML' => Illuminate\Html\HtmlFacade::class,
