Nginx rewrite rules for prestashop, how to setup, debug and enable?

I want to change from Apache to Nginx+Php-Fpm for performance reasons. Currently I can see homepage of my website (in test environment) but any friendly url that worked in Apache does not work now.

I have already converted rules to nginx rules but I don't have any way to test it because, every click on some url of the site turns into my browser download the php file!

for example

I click on

and my browser download a php file :-/

Environment Test is

* PHP 5.3.17 (cli) (built: Sep 13 2012 06:45:07)
Copyright © 1997-2012 The PHP Group
Zend Engine v2.3.0, Copyright © 1998-2012 Zend Technologies

* nginx -v
nginx version: nginx/1.0.15


Here it is my nginx virtual host config:

server {
server_name site.com

Worst problem is I don't have some experience to debug the problem :-/ Very new with Nginx
Any comment will be appreciated,

Thanks

Ok, I've fixed my own issue! It was so easy by the way, only was to change the location of the rules

I've moved all rules of

location /{
.... rules...
}

to

server {

...here rules works...

}

Then I reload nginx and that's it!

service nginx reload

I hope this can be useful for some desperate guy like me.

Best regards,

Ruben
