Hey, you need to enable debug mode in app.php under app/config. If it's production server, you should NOT have this on, as it exposes your code to the public. For local development you should try Homestead :)

Yes. I enabled

After checking on server. I see that error was writen to nginx error log file : http://pastebin.com/9T3qMnnq

But why it wrote to here ? It should show on debug page of Laravel same as other error!

Slightly related, but I was having an issue with Homestead 2 not rendering the Laravel 4.2 debugger but instead Nginx was displaying I presume it's default 404 page. Even with appropriate debug settings per environment I could not get this working.

Finally the above advice to simply comment out the error_page 404 /index.php; in my nginx.conf file worked. Still learning Laravel so not sure why I needed to do this but thought to post it up here for anyone else.
