Domain Mapping Issue

I got wordpress multisite all set up, subdomains working fine.

Once I uncomment the following lines from my server config… nothing.

nginx fails to reload.

server {

# Uncomment the following line for domain mapping
#listen 80 default_server;

server_name example.com *.example.com;

# Uncomment the following line for domain mapping
#server_name_in_redirect off;

access_log   /var/log/nginx/example.com.com.access.log rt_cache;
error_log    /var/log/nginx/example.com.com.error.log;

root /var/www/example.com.com/htdocs;
index index.php index.htm index.html;

include common/w3tc.conf;
include common/wpcommon.conf;
include common/locations.conf;

}

Can you provide me output for this command, by uncommenting the suggested lines

nginx -t
