fb_stream with editor role

I give to editor role the permissions to use fb_stream module and he can see the form on edit-node page correctly, but when he click on save button nothing happen on facebook page. When I log-in as administrator everything is working and if I edit a node and check "send to facebook" checkbox it's sent to the facebook page.

On Reports -> Recent log messages, when I send as editor I have the error:

Failed to post content to Facebook.: fb_graph failed querying 138934052840914/feed. OAuthException: Error validating application. Application has been deleted.

But when I send as Administrator I have no error.

Thanks to all.
