여기 게시판에서 검색을 해보니 첨부파일 늘리는 방법이 있길래 그걸 보고
config, sql_write.sql, gbupdate.php 파일을 아래처럼 수정을 했습니다.

그런데 테스트를 해보려고 글쓰기를 하면 첨부파일은 6개가 나오는데
저장을 하면 아래처럼 에러가 뜨네요.

1054 : Unknown column 'wr_file5' in 'field list'

원인을 아시는 분이 계시면 답변 부탁드립니다. 
혹시 phpadmin에서 sql명령어를 쳐야 된다면 어떤 것을 쳐야하는지 알려주시면 감사드리겠습니다.

게시판 검색으로는 찾기가 어렵네요.
꼭 부탁드립니다. ^^
