Yes, the password is entered correctly, the configuration tool available to me all the information online. One can see avatars, etc. etc.
You can see the info offline even if you have the wrong password.
I am a bit stuck as the only thing I can think is that it could be down to a network type issue or your ISP ?? (or perhaps last.fm not working properly in your country). I have been listening to music today and everything has scrobbled fine.#
Can you try and delete the users in the audioscrobbler plugin completely then close config. Then go back and in and re-add ?
