Error code 403 returned for Google translate pages

Hi Guys

Sorry not sure where i should have submitted this issue. When checking my Google Analytic reports i noticed the google translate URL is returning error code 403.

http://www.shoppersbase.com/translate_c?depth=2&nv=1&rurl=translate.google.com&sl=auto&tl=el&u=http://www.shoppersbase.com/36706/could-new-285-hair-cream-by-kerastase-be-the-cure-for-baldness/&usg=ALkJrhgEkr6i7UvWWANNwVcT_tICMUx91w

Please kindly advice me where i need to edit my .htaccess files for this url to be fix.

Thanks for your support.
