Laravel 5. Debug mode

This line in your config file, 'debug' => env('APP_DEBUG', true), may be the cause of your issue.

It is saying; set debug to the value defined in my .env file, and if there is none then use true.

As such it is looking at APP_DEBUG=false in your .env file, even though you have set the second parameter to true.

Try updating the setting in your .env file to true.
