+피디님 말씀듣고 파일첨부했어요. 죄송합니다 ㅠㅠ

제가 홈페이지를 만들면서 아이프레임으로 php파일을 불러오게끔 하려고 합니다.
외부로그인을 달려고 하는데 어제부터 이것때문에 씨름중이에요
어떻게 고쳐보아도 자꾸만 에러가 나옵니다 ㅠㅠ
질문게시판에 검색해서 찾아봐도 해결되는 답변이 없어서 직접 질문 적습니다 ㅠㅠ

로그인페이지 (log.php) 내용
<?
include_once("./_common.php");
include_once("$g4[path]/lib/outlogin.lib.php");
include_once("$g4[path]/lib/latest.lib.php");
?>

<?=outlogin("basic"); //외부로그인 ?>
