Hi Ling,
i can´t understand why are you looking solutions over old versions of Xoops&modules existing very new & comfortable versions, better like olders !
Update your sistems (not hard work), get all benefits inside it & forget to found any compatibility. Maybe you webser are working under PHP5 & many of you really old modules can´t work it. Don't loose your time, do the right, go ahead!
Regards
