위처럼 뜨는건 head.sub.php를 인클루드 안시켜서 나는 오류인가요?;
인클루드 시켜야한다면 소스의 어느부분을 고쳐야하는지요
어제 질문올렸는데 고마우신 몇몇분의 도움이있었지만 아직도 해결을 못봣어요ㅠ

head.sub.php 소스의 32~38 라인 입니다

--------------
header("Content-Type: text/html; charset=$g4[charset]");
$gmnow = gmdate("D, d M Y H:i:s") . " GMT";
header("Expires: 0"); // rfc2616 - Section 14.21
header("Last-Modified: " . $gmnow);
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: pre-check=0, post-check=0, max-age=0"); // HTTP/1.1
header("Pragma: no-cache"); // HTTP/1.0

register.php 소스이구요.
------------------
<script language="javascript" src="<?=$g4[path]?>/js/md5.js"></script>
