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
朋友，旭日正在升起，每一份付出，
