제로보드 폴더에 있는 _head.php 파일을 나모같은 웹에디터가 아닌 메모장이나 워드패드로 오픈하보신후 대략 17번째줄부터 시작하는 아래의 소스를 찾은후

/***************************************************************************
* 현재 _head.php를 호출하는 파일이 게시판 관련 파일인지 검사

$_zb_file_list = array("apply_vote.php","comment_ok.php","del_comment.php","del_comment_ok.php",
"delete.php","download.php","list_all.php","view.php","vote.php","write.php","write_ok.php",
"zboard.php","image_box.php"'이부분');
$_zb_c = count($_zb_file_list);
for($i=0;$i<$_zb_c;$i++) {
if(eregi($_zb_file_list[$i],$PHP_SELF)) { $_zboardis = TRUE; break; }
else $_zboardis = FALSE;
}

$_zb_file_list = array("apply_vote.php","comment_ok.php","modify_comment.php","modify_comment_ok.php","del_comment.php","del_comment_ok.php","delete.php","download.php","list_all.php","view.php","vote.php","write.php","write_ok.php","zboard.php","image_box.php");

위의 저 소스의 끝에 rosun.php 를 추가해서 넣어보세요.
