Go to Laravel project -> app folder-> config folder -> app.php set
'debug' => false,
This will show a simple error page like Ops! Something went wrong.
Edit:
Laravel App facade provides a way to way catch the exceptions using error method as mentioned in the Laravel docs
App::error(function(Exception $exception)
{
// handle your exception
});
You can place App::error method in the filters.php
and Laravel is using Symfony to display those pages if you want to further go down. I have not really tried to change this thing, maybe someone will come up with a better answer.
