Laravel 4.2不适用于公共服务器

I installed laravel 4.2 and in my wamp server everything goes right.

But when I copied all project to my FTP server, I get white screen window with no errors. Just white screen.

The only thing that I have done was to remove the public folder from the URL via this url -> http://creolab.hr/2013/03/removing-the-public-segment-in-a-laravel-4-app/

I did that on Laravel 4.0 and when I copied everything works fine, but with this 4.2 its diferent.

Any help?
