[dedecms视频发布]dedecms后台登录后空白的问题

【www.bbyears.com--dedecms教程】

PHP5.4中已经不再使用如下图片灰色选中这样的语句，所以后台打开一片空白。用notepad++打开include文件夹下面userlogin.class.php文件。找到以下代码（288行、291行、294行、297行、300行、303行）：

word-wrap: break-word; background-image: url(http://zhuqidong.gotoip2.com/templets/caizi/images/code-bg.png); background-color: rgb(255, 255, 255);\">        if($this->userID != '' && $this->userType != '')
        {
            global $admincachefile,$adminstyle;
            if(empty($adminstyle)) $adminstyle = 'dedecms';

            @session_register($this->keepUserIDTag);
            $_SESSION[$this->keepUserIDTag] = $this->userID;

            @session_register($this->keepUserTypeTag);
            $_SESSION[$this->keepUserTypeTag] = $this->userType;

            @session_register($this->keepUserChannelTag);
            $_SESSION[$this->keepUserChannelTag] = $this->userChannel;

            @session_register($this->keepUserNameTag);
            $_SESSION[$this->keepUserNameTag] = $this->userName;

            @session_register($this->keepUserPurviewTag);
            $_SESSION[$this->keepUserPurviewTag] = $this->userPurview;

            @session_register($this->keepAdminStyleTag);
            $_SESSION[$this->keepAdminStyleTag] = $adminstyle;

            PutCookie('DedeUserID', $this->userID, 3600 * 24, '/');
            PutCookie('DedeLoginTime', time(), 3600 * 24, '/');
            
            $this->ReWriteAdminChannel();
            
            return 1;
        }

找到以上代码，以 @session_register开头的这6句代码，将其注释掉。如下：

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

            //@session_register($this->keepUserIDTag);
            $_SESSION[$this->keepUserIDTag] = $this->userID;

            //@session_register($this->keepUserTypeTag);
            $_SESSION[$this->keepUserTypeTag] = $this->userType;

            //@session_register($this->keepUserChannelTag);
            $_SESSION[$this->keepUserChannelTag] = $this->userChannel;

            //@session_register($this->keepUserNameTag);
            $_SESSION[$this->keepUserNameTag] = $this->userName;

            //@session_register($this->keepUserPurviewTag);
            $_SESSION[$this->keepUserPurviewTag] = $this->userPurview;

            //@session_register($this->keepAdminStyleTag);
            $_SESSION[$this->keepAdminStyleTag] = $adminstyle;

            PutCookie('DedeUserID', $this->userID, 3600 * 24, '/');
            PutCookie('DedeLoginTime', time(), 3600 * 24, '/');
            
            $this->ReWriteAdminChannel();
            
            return 1;
        }

注释掉这6行代码后，保存。然后再进行登录后台，后台恢复正常。
