Hey alexander,
Perhaps you can temporary disabled this settings first from your
backend > Easysocial > settings > Facebook > Allow Updating Timeline - NO and see Facebook user is it can submit stream?
Regarding this issue, I believe you haven't get approve by Facebook reviewer for this Facebook user permission "publish_actions" from your Facebook app.
You can follow this similar documentation here :
http://stackideas.com/docs/easyblog/administrators/autoposting/setting-up-facebook-app
Once Facebook reviewer approve this `publish_actions` user permission, so your Facebook user have permission to autopost their stream content appear on their Facebook user profile page.
Hope this will helps.
