해당게시판의 스킨도 basic 으로 맞는데요,
문제는 글쓰기 스킨이 아니라 글 쓰기 자체가 되지 않는거예요.
계속 "정상적인 접근이 아닙니다"는 문구만 나오네요.
참고로 그 스킨을 첨부할게요

스킨을 새로 업로드해 보니 자동등록방지용 코드 이미지가 안뜨네요

현재 설치된 js폴더에는 jquery-1.4.2.min.js, jquery.kcaptcha.js가 없고요

head.sub.php에도 <script type="text/javascript" src="<?=$g4['path']?>/js/jquery-1.4.2.min.js"></script>  jquery-1.4.2.min.js가 comm.js로 되었네요

알려주신대로 새로 스킨을 설치했는데 저희 js하고 맞질 않아서 자동등록 방지 코드 부분만 삽입했습니다. 잘 해결 되었는데요. 오류 메시지가 뜨는데 무슨소리인지 도통 모르겠네요
