PHPCMS 2008 RSS订阅不更新的解决方法

近日，有站长咨询关于PHPCMS 2008 RSS订阅不更新的问题，经过查发现了解决方法，如下，共修改2个位置：

1.rss.php文件查找

$sql = "SELECT `title`, `description`, `url`, `inputtime`, `thumb`, `keywords` FROM ".DB_PRE."content WHERE `status` = '99' ORDER BY `catid` DESC LIMIT 0 , 20";

改成

$sql = "SELECT `title`, `description`, `url`, `inputtime`, `thumb`, `keywords` FROM ".DB_PRE."content WHERE `status` = '99' ORDER BY `contentid` DESC LIMIT 0 , 20";

2.RSS.php继续查找

$sql .= " ORDER BY `catid` DESC LIMIT 0 , 20";

改成

$sql .= " ORDER BY `contentid` DESC LIMIT 0 , 20";
