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`,`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";
