1、創建 update_code.php 文件，并將以下代碼粘貼到本文件：

<?php

require_once ('global.php');

require_once(R_P.'admin/cache.php');

$db_siteid = generatestr(32);

setConfig('db_siteid', $db_siteid);

$db_siteownerid = generatestr(32);

setConfig('db_siteownerid', $db_siteownerid);

$db_sitehash = '10'.SitStrCode(md5($db_siteid.$db_siteownerid),md5($db_siteownerid.$db_siteid));

setConfig('db_sitehash', $db_sitehash);

updatecache_c();

echo 'success';

function generatestr($len) {

mt_srand((double)microtime()*1000000);

$keychars = "abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWYXZ";

$maxlen = strlen($keychars)-1;

$str = '';

for ($i=0;$i<$len;$i++){

$str .= $keychars[mt_rand(0,$maxlen)];

}

return substr(md5($str.microtime().$GLOBALS['HTTP_HOST'].$GLOBALS['pwServer']["HTTP_USER_AGENT"].$GLOBALS['db_hash']),0,$len);

}

function SitStrCode($string,$key,$action='ENCODE'){

$string = $action == 'ENCODE' ? $string : base64_decode($string);

$len = strlen($key);

$code = '';

for($i=0; $i<strlen($string); $i++){

$k = $i % $len;

$code .= $string[$i] ^ $key[$k];

}

$code = $action == 'DECODE' ? $code : str_replace('=','',base64_encode($code));

return $code;

}

?>

2、將文件上傳到根目錄，運行 您的站點地址/update_code.php

3、后臺重新注冊
