nginx showing blank PHP pages

Question

I have setup an nginx server with php5-fpm. When I try to load the site I get a blank page with no errors. Html pages are served fine but not php. I tried turning on display_errors in php.ini but no luck. php5-fpm.log is not producing any errors and neither is nginx.

nginx.conf

server {
    listen 80;
    root /home/mike/www/606club;
    index index.php index.html;
    server_name mikeglaz.com www.mikeglaz.com;
    error_log /var/log/nginx/error.log;
    location ~ \.php$ {
            #fastcgi_pass 127.0.0.1:9000;
            # With php5-fpm:
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;
    }
}

EDIT

here's my nginx error log:

2013/03/15 03:52:55 [error] 1020#0: *55 open() "/home/mike/www/606club/robots.txt" failed (2: No such file or directory), client: 199.30.20.40, server: mikeglaz.com, request: "GET /robots.txt HTTP/1.1", host: "mikeglaz.com"

Answer 1

replace

include fastcgi_params;

with

include fastcgi.conf;

and remove fastcgi_param SCRIPT_FILENAME ... in nginx.conf
