Laravel 5 blade shows a blank page when there is e

Question

In laravel 4 when you try to render a view that does not exists in app\views or a view with undefined variables laravel will throw an exception or show error that helps with debug.

I have a fresh installation of laravel 5.0.13 and am having a tough time troubleshooting a blade template that shows a blank page when i render a view that does not exists instead or a template with undefined variables instead of throwing an exception or error which will clue me in when debug.

I have installed filp/whoops:~1.0. but still recieve a blank page

class ProfileController extends Controller
{

    public function index()
    {
        return view('indexx'); //this view does not really exist
    }
}

The file indexx does not exist in my resources/views and i expect Laravel to throw an exception but am getting a blank page instead, why?

Also when i render a view that exists with some undefined variables i simply get a blank page

Example:

class ProfileController extends Controller {

    public function index()
    {
        return view('index'); //this view exists
    }

}

The content of resources/views/index

{!! $this_variable_was_not_passed_an_I_expect_error !!}

As you can see in the view file above the variable does not exist by laravel will simply show a blank page instead of throwing an exception or some debug error.

Also to note i change my laravel default view in config/views

'paths' => [ 
//realpath(base_path('resources/views')) 
realpath(base_path('resources/themes/default')) 
],

And laravel was able to render views from resources/themes/default as long as there is no error in the template however, if any error was encountered such ar undefined variable a laravel displays a blank page instead of showing error message

Also to mention that I install virtual box and vagrant on window 7

Could this be a bug or something? Please assist.

Answer 1

An alternative solution which helped me, is running

composer install 

I deployed with git which auto ignores some files. running composer install fixed it for me.

Answer 2

I don't really know why this happened but its now working as required after i run

vagrant destroy to destroy homestead VM

and then vagrant up - to create the VM

The error messages has now showing up instead of blank page:

Answer 3

I got the same problem but here comes the reason and the solution: The logfiles in storage/logs needs to be owned/writable by the webserver user. Otherwise L5 gives you a blank page.

I run "php artisan ..." always as root. If an exception was thrown and Laravel creates a new logfile, then it's owned by root. On my Debian i run in the project root folder: chown www-data.root * -R to solve this problem.

Answer 4

Try to change permission on the storage folder:

chmod -R 0777 storage

It worked for me.
