What value did you change in the config ?

[asanzred]

Nothing, just installed on my laravel project with composer

I have this problem too, exactly same. But there is no problem for the WAMP. Any solution here? because of i using share host ?

My php version is 5.4.29

I noticed this happened to me after installing with composer, but forgetting to add Thujohn\Pdf\PdfServiceProvider to the list of providers in app/config/app.php.

This happens as since Laravel doesn't have access to the config values, it returns an empty array which it attempts to define.
