Thread:Extension:LiquidThreads/FAQ/Access problem

We should implement our wiki on shared wiki site(like wikia or etc) .As far as I read we must have some modification on Localsetting.php and DB on using the LiquidThreads extension but we don't have access to the field of database or Localsetting.php so Is it possible to use LiquidThreads extension when we have a situation like as I explain. Thanks
