не помогло :(

оставил вообще:
server {
listen 80;
server_name site.ru;
location / {
expires epoch;
fastcgi_pass unix:/tmp/fcgi.sock;
fastcgi_read_timeout 30;
fastcgi_send_timeout 30;
fastcgi_intercept_errors on;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param script_filename /home/art/www/site.ru$fastcgi_script_name;
}
}
