You say you "installed the latest nginx"? What were you using before? Did you install NGINX mainline? NGINX stable? NGINX unit?
Did you install it via the OS process (APT, YUM) or did you install it manually? Did it advise that it was changing any control files during the upgrade (if this was an update to an existing install) and did you pay attention to what those changes were?
