그누커머스 상품 위젯 에러 및 질문

안녕하세요. 그누커머스로 테스트작업중입니다. 

전용테마를 적용할려다가 상품위젯에러가 나서 로그를 찾아보니 에러가 나더라구요.

PHP message: PHP Stack trace:

이쪽부분이긴한데 .. 일단

        if( self::$attr['category'] ){  //카테고리가 있다면

            $query_args = self::get_categoty_args( self::$attr['category'] );

        }

get_categoty_args 

get_category_args 

하니까 에러는 일단 안납니다 (..) 한번 확인 부탁드려요. 

그리고 분류(카테고리)명이 한글일때 잘..작동안하는것같습니다.

두번째 질문은

배송주소지가 필요없는 상품은 아예 옵션을줘서 안받을수있는지 궁금합니다. (디지털 경품추첨용 상품이라던가..)
