1、找include/userlogin.class.php里面的keepuser()函数，
2、把@session_register 全部改写， 虽然不知道这个@是什么意思把@session_register($this幻腾寂埒->keepUserIDTag); 注释掉，然后改为if (!isset($_SESSION[$this->keepUserIDTag]))
3、全部有6个。如下：坡纠课柩if (!isset($_SESSION[$this->keepUserIDTag]))//刺胳挤萧@session_register($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。
