某基友在某地门户上班..网站总让人日..so..让吾等小菜帮忙看一下   菜文 勿喷  抛砖引玉专用

\common\lib\FCKeditor\editor\filemanager\upload\php\config.php
 
$Config['AllowedExtensions']['File'] = array() ;
$Config['DeniedExtensions']['File'] = array('php','php2','php3','php4','php5','phtml','pwml','inc','asp','aspx','ascx','jsp','cfm','cfc','pl','bat','exe','com','dll','vbs','js','reg','cgi') ;

if(file_exists($insLockfile))
{
        exit(" 程序已运行安装，涛涛电脑知识网，如果你确定要重新安装，涛涛电脑知识网，请先从FTP中删除install/install_lock.txt！");
}
?>
