Nginx trys to download file instead of displaying

I install Nginx and have a subdomain and domain. The subdomain has php5-fpm and wordpress. It works fine and is in one sites-available file symlinked to sites-enabled. The domain doesn't have php and has a file also symlinked. Even after restarting the server when I go to the domain it tries to download the html file. Here is my sites-available page for the domain:

       server {
        server_name www.example.us;
        rewrite ^(.*) http://example.us$1 permanent;
    }

    server {
            listen 80;
            server_name example.us;
                    root /var/www/example;
            index index.php;
            autoindex on;
            autoindex_exact_size off;
            include /etc/nginx/security;
    # Logging --
    access_log /var/log/nginx/example.us.access.log; 
    error_log /var/log/nginx/example.us.error.log notice;
            # serve static files directly
            location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt)$ {
                access_log off;
                expires max;
            }

#            location ~ \.php$ {
#           try_files $uri =404;
#                    fastcgi_pass unix:/var/run/php5-fpm/example.us.socket;
#                    fastcgi_index index.php;
#                    include /etc/nginx/fastcgi_params;
#            }
    }

The nginx.conf file is:

worker_processes 4; 
pid /var/run/nginx.pid;

    worker_connections 768;
