WAMP Server 安装dedeCMS 后，登陆后台管理页面空白解决方案

找include/userlogin.class.php里面的keepuser()函数，
把@session_register 全部改写， 虽然不知道这个@是什么意思
把@session_register($this->keepUserIDTag);    注释掉，然后改为
if (!isset($_SESSION[$this->keepUserIDTag]))
全部有6个。
如下：
if (!isset($_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] = $adminstyle;
然后就可以登入后台了。
问题原因：
session_register，php5.4移除了这个函数，版本里说明，继续使用该函数会产生错误。
if (!isset($_SESSION[$this->keepUserTypeTag]))改成这个方式就可以了
