access log debugging

[Ian Evans]

Not sure if it's the heat and I'm tired...

Had access logs off for a long time. Decided to start it up again to try 
and track down a bot issue.

Added access_log /var/log/nginx/access.log; to my server config. 
Restarted. It creates a log file. Notice it has root:root permissions, 
while the error logs are nginx:adm.

Wait. Access log stays at zero bytes. Go to a few pages on site. Zero.

I'm missing something simple, right?
