Question

dedecms 打开首页跳转到install/index.php,栏目页打不开，后台显示空白，求解决

Answer 1

网上有两种解决方法：
一种是说你曾用记事本编辑过dede的php文件
2是说你得修改
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。

我用的第二种方法解决的

没安装的原因 ，你安装了也不会直接跳转到install 这个文件中
