第一种解决方案：
织梦CMSdedecms登录后台出现500错误大部分是这样，也可以把服务器上的php版本降为5.3或者5.2的就可以了。原因很简单，服务器php环境用的php5.4，而dedecms的login.php中使用了一个被php5.4废除了的函数：session_register()
方法很简单，直接注释掉，不用进行注册就可以声明session。
在“include/userlogin.class.php”中查找“function keepUser()”
大概在281行，把keepUser()函数下的 @session_register(); 整段注释掉（删除也可以），代码如下：
function keepUser()
{
if($this->userID != '' && $this->userType != '')
{ global $admincachefile,$adminstyle;
if(emptyempty($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, '/');
$this->ReWriteAdminChannel();
return 1;
}
else
{
return -1;
}
}
另外的解决方法就是在“include/userlogin.class.php”中声明一个函数
function session_register()
{
return true;
}
第二种解决方案：
dedecms不支持PHP5.3、PHP5.4及以上版本，主要原为是php5.4的版本废除了session_register函数 ，可以采用如$_SESSION[$this->keepUserIDTag] = $this->userID;。
打开“include/userlogin.class.php”，将287行到308行：
@session_register($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, ‘/’);
第三种解决方案：
找到data文件夹下的safe里的inc_safe_config.php，看看结尾处是否缺少符号
