in /usr/share/accounts/providers/facebook.provider

worked for me to fix it.

Everyone who this isn't working for, are you adding the
          <setting type="as" name="AllowedSchemes">['https','http']</setting>
inside the
        </group>
      </group>
    </group>
  </template>
</provider>
of the xml document?
