Nit: This line is too long (but I think the message is pretty good), could you
wrap it something like this?

logging.warning("Unable to import sitescripts, proceeding with empty "
                "subscriptions list.")

Note:
 - Plus symbol was omitted deliberately
 - I also added a full stop

Done.
