Find my iPhone not working

For the Find My iPhone to work, it has to be first activated in iCloud, the device has to have an active internet connection, you have to log into iCloud with the same Apple ID and password as the one on the phone. Are all of these things in place? Otherwise try this support document for troubleshooting the system. iCloud: Troubleshooting the Find My iPhone app

Check the support document above, or you can also use the standard user troubleshooting steps, restart, reset, restore from backup, restore as new.

Is your device jailbroken by any chance?

OK, just checking.... We have seen some unsolicited turning off of Find My iPhone on jailbroken devices, so thought I'd ask....

Is it possible that this occurred immediately following an iOS upgrade? That is the only other situation that I have seen.

Updated to iOS8 today, now Find My iPhone works as before but there's no map. The phone shows on a grid. I've tried several other iPhones in the family over the past 4 hours, all with the same results. How did I lose the map? It's in my phone and can be accessed from the map app. Here's what I get:

I would try doing a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. I just went into mine and it is working fine. It just appears that you are not accessing the map data.

Reset did it! Thanks for suggesting it.

You're welcome.
