DedeCMS后台500错误一种原因是不支持PHP5.3、5.4及以上版本

　　我们在迁移网站的时候，可能会出现DedeCMS后台500错误，有可能是因为dedecms不支持PHP5.3、5.4及以上版本，这时我们要改动一些设置才能修复成功。跟着ytkah来修改配置文件吧。首先打开 include/userlogin.class.php这个文件，在287行到308行原内容如下：

@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, ‘/’);

替换成

if(empty($adminstyle)) $adminstyle = ‘dedecms’;

//@session_register($this->keepUserIDTag);

$_SESSION[$this->keepUserIDTag] = $this->keepUserIDTag;

$_SESSION[$this->keepUserIDTag] = $this->userID;

//@session_register($this->keepUserTypeTag);

$_SESSION[$this->keepUserTypeTag] = $this->keepUserTypeTag;

$_SESSION[$this->keepUserTypeTag] = $this->userType;

// @session_register($this->keepUserChannelTag);

$_SESSION[$this->keepUserChannelTag] = $this->keepUserChannelTag;

$_SESSION[$this->keepUserChannelTag] = $this->userChannel;

//@session_register($this->keepUserNameTag);

$_SESSION[$this->keepUserNameTag] = $this->keepUserNameTag;

$_SESSION[$this->keepUserNameTag] = $this->userName;

//@session_register($this->keepUserPurviewTag);

$_SESSION[$this->keepUserPurviewTag] = $this->keepUserPurviewTag;

$_SESSION[$this->keepUserPurviewTag] = $this->userPurview;

// @session_register($this->keepAdminStyleTag);

$_SESSION[$this->keepAdminStyleTag] = $this->keepAdminStyleTag;

$_SESSION[$this->keepAdminStyleTag] = $adminstyle;

PutCookie(‘DedeUserID’, $this->userID, 3600 * 24, ‘/’);

PutCookie(‘DedeLoginTime’, time(), 3600 * 24, ‘/’);

　　覆盖文件，刷新后台看看，是不是已经没有错误提示了？如果还有错误，您可以参考dedecms后台左侧菜单500错误怎么处理
