Noteshelf Sync

[Graham Jenkins 0]

I am using Evernote Basic and until recently the automatic sync from my Noteshelf notebooks has worked just fine. However this message has started to appear

"Unable to authenticate with Evernote" and the sync between Noteshelf and Evernote no longer works.

Can anyone suggest a fix?

You might check into Evernote, at the account settings page and see if Noteshelf is still authorized.  The authorization is created with a fixed time.
