you can try the following
in modules/snsproducttabs/snsproducttabsclass.php find and change
(($id_category && $field_filter = null) ? ' AND c.<code>id_category</code> IN ('.implode(',',$id_category).')' : '').
=>
' AND c.<code>id_category</code> IN ('.implode(',', array_map('intval', $id_category)).')'.
if still issue, please give me your Access Info. I will check it on your site. Thanks!
