导读:dedecmsdedecms今天下载了一个新版的dedecmsv5.7安装之后突然发现登录后台发现空白了，我php环境是使用的php5.4系统，经过百度php5.4把@session_re织梦模板免费dede免费模板。

解决方法：

打开 /userlogin.class.php 文件，在当前文件搜索keepUser(),然后把这个下面的@session_register();给注释掉就行了！

当然要不影响，可以改成

 代码如下 if (!isset($_SESSION[$this->keepUserTypeTag]))

修改完的函数：

 代码如下

function keepUser()     {         if($this->userID != '' && $this->userType != '')         {             global $admincachefile,$adminstyle;             if(empty($adminstyle)) $adminstyle = 'dedecms';

   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[$th织梦文章模板is->keepAdminStyleTag]))    //@session_register($this->keepAdminStyleTag);    $_SESSION[$this->keepAdminStyleTag] = $adminstyle;             PutCookie('DedeUserID', $this->userID, 3600 * 24, '/');             PutCookie('DedeLoginTime', time(), 3600 * 24, '/');                         $this->ReWriteAdminChannel();                         return 1; }    else {      return -1; }
