윈도우서버에서 그누보드(아미나빌더)를 사용중입니다.

별다른 소스를 건들지 않은거 같은데요.

어느순간 아래와 같은 에러가 에러로그파일에 계속 쌓입니다.

사이트 이용에는 전혀 문제가 없는데

로그파일이 계속 쌓이다보니 계속 지워줘야되네요...

에러가 생기는 아이피들은 이상하게 봇 아이피가 대부분입니다.(구글봇,빙봇등)

head.sub.php

117 118 121 번째 줄을 보면

<script src="<?php echo NA_URL ?>/js/common.js?ver=<?php echo G5_JS_VER; ?>"></script>  
<script src="<?php echo G5_JS_URL ?>/wrest.js?ver=<?php echo G5_JS_VER; ?>"></script>
<script src="<?php echo NA_URL ?>/js/nariya.js?ver=<?php echo G5_JS_VER; ?>"></script>

이 라인인데요..

어디를 손봐야할까요??
