Received an invalid response from the server with taxonomy translation

hello,guys.
i got a big problem,i read most of the issues here but i cannot find a solution for my problem,
i have a bi lingual websites with 2 language.
when ever i enable "Set language to vocabulary. The vocabulary will have a global language and it will only show up for pages in that language." for the vocabulary ,i got this error "Received an invalid response from the server with taxonomy translation".
is it any conflict between HS and i118n Taxonomy translation?
i use HS 6.x-3.7 version.what should i do??
is there any body knows how to solve this problem??
thanks every one.
