워드프레스 메인 수정 어디서하나요?

index 열어보면

<script language=javascript>

var mobileKeyWords = new Array('iPhone', 'iPod', 'BlackBerry', 'Android', 'Windows CE', 'LG', 'MOT', 'SAMSUNG', 'SonyEricsson','Mobile','Nokia','webOS','Opera Mini','opera mobi','SonyEricsson','Windows Phone','IEMobile','POLARIS');

for (var word in mobileKeyWords){

    if (navigator.userAgent.match(mobileKeyWords[word]) != null){

location.href = "/m/";

        break;

    }

}

</script>

<?php

/**

require( dirname( __FILE__ ) . '/wp-blog-header.php' );

모바일이동 스크립트랑 저것만 꼴랑써있는데.. 

/wp-blog-header.php 이거 따라들어가도 별내용 써있지도않고.. 

메인페이지 코드수정하려면 어디로가야하나요..
