Internal Server Error 500

[TechKat]

I've done everything the installation has asked but I get a Internal Server Error 500.

return dd(PDF::load($html, 'A4', 'portrait')->output());

The code is within a controller that a route uses. The page is just blank, but Inspect Element comes up with error 500.

I got the same error and when checked apache error logs, I saw:

PHP Fatal error:  Call to undefined method Thujohn\\Pdf\\PdfFacade::load()

I found my mistake. In my case, I had app/config/local/app.php with custom providers array. That array was overriding my changes with providers array in app/config/app.php (including new PDF service provider). So I wrapped array in local config with append_config(). Hope it helps somebody.
