Last.fm Wrong Username and Password Error

[bjpetro]

I am running Spotify on Android on my phone, and every time I open the app I receive a Last.fm error that says Wrong Username and Password. I don't want to scrobble from my phone. I've turned off Last.fm Scrobbling on my mobile device and I've logged off of Spotify scrobbling on my Last.fm account, but whenever I go to Spotify settings from the mobile app, scrobbling is always turned on even when I've turned it off numerous times. Can anyone help? Thank you!

Hi. Try deleting cache and data, and be sure to deactivate lastfm scrobbling at preferences.

Thank you for the suggestion. However, I'd like to use that as a last resport if possible because deleting the cache and data will require me to re-download all my offline playlists.

I solved it by changing my last.fm password. I think password on last.fm API should met some rule first.
