Don't know what happens. The same project, in Windows XAMPP it's ok but in my Mac with laravel Valet it don't show anything. The error log said "local.ERROR: Debugbar exception: A non well formed numeric value encountered". I'm on Laravel 5.2
Which php version?
PHP 7. I think because it is on Nginx (Valet 2). I tried to use XAMPP for Mac that use Apache and it works.
I've the same error but i run the application with php artisan serve
My spec:
Same error here when upgraded my version of Laravel Homestead
PHP version 7.1
DebugBar version 2.2.2
Laravel version 5.1.35
I solved this by updating my composer dependencies with composer update.
This issue had to do with the symfony/var-dumper library. This issue with php 7 was already reported (https://github.com/symfony/symfony/pull/19379) and fixed (https://github.com/symfony/var-dumper/blob/v2.7.16/Cloner/VarCloner.php#L318) since var-dumper 2.7.16.
I have composer.lock under version control so it would always pull versions from that file, and it's been a while since I updated my project's dependencies, so I had an old version of debugbar, which in turn had an older version of var-dumper (2.7.13).
Hopefully it will be the solution for others as well.
