File isn't where locate says it is

I'm trying to find a certain file for apache so I used the locate command to find it, however, when I go to the directory that locate says it is in, the file isn't there. Does anyone know why this might be? I've tried switching to the super user but it still doesn't show up. Thanks!

The locate command uses a database, which is updated about once a day. While it gives fast results, it isn't necessarily accurate. If locate says a file exists, but it isn't there, it was moved or deleted after the last database update. Also see A file shows in “locate” command but don't exist. Why?
