找到include/userlogin.class.php文件，打开文件
里面有一个keepuser()函数，它是用session_register来注册一个session变量，但是在php5.4中已经移除了这个功能，
如果使用的该php版本肯定会出错的，不过我们可以修改下代码：
把
@session_register($this->keepUserIDTag);
注释掉，然后改为
if (!isset($_SESSION[$this->keepUserIDTag]))
一共有六个，全部改为下面这样：
if (!isset($_SESSION[$this->keepUserIDTag]))
//@session_register($this->keepUserIDTag);
$_SESSION[$this->keepUserIDTag] = $this->userID;
if (!isset($_SESSION[$this->keepUserTypeTag]))
//@session_register($this->keepUserTypeTag);
$_SESSION[$this->keepUserTypeTag] = $this->userType;
if (!isset($_SESSION[$this->keepUserChannelTag]))
//@session_register($this->keepUserChannelTag);
$_SESSION[$this->keepUserChannelTag] = $this->userChannel;
if (!isset($_SESSION[$this->keepUserNameTag]))
//@session_register($this->keepUserNameTag);
$_SESSION[$this->keepUserNameTag] = $this->userName;
if (!isset($_SESSION[$this->keepUserPurviewTag]))
//@session_register($this->keepUserPurviewTag);
$_SESSION[$this->keepUserPurviewTag] = $this->userPurview;
if (!isset($_SESSION[$this->keepAdminStyleTag]))
//@session_register($this->keepAdminStyleTag);
$_SESSION[$this->keepAdminStyleTag] = $adminstyle;
修改PHP程序代码方法如上。
