"Wrong file type, please select again" when choosing a ringtone I have a Nexus 5, all my ringtones and notification sounds returned to default, and when I try to set any file as a sound I get this message: 


  Wrong file type, please select again


I get the same message no matter what file type I choose, including the files that were my sounds until this morning. I tried to delete cache memory and reboot but that did nothing.
José Mejuto Was correct in his 2nd Point.

deleting the /.nomedia file has no effect.


1: Go to "Settings -> Apps (All) -> Media storage"
2: Clear Cache &amp; Data
3: Change your ring tone or notification tone


Thanks José :)
