确认你在安装时所使用的表前缀为 pa_ ,如果不是,把下面的sql中的 pa_ 替换成你所安装时所使用的表前缀.运行以下sql.
ALTER TABLE `pa_articlerate` ADD `ipaddress` VARCHAR(16)  NOT NULL;
ALTER TABLE `pa_articlerate` ADD INDEX ipaddress (ipaddress);


登陆后台,修改游客所在的用户组权限,把"可以对文章评分?"设置为"是"
修改 feedback.php 
查找:

if ($pauserinfo[userid]==0) {
    show_nopermission();
}

$checkvote = $DB->fetch_one_array("SELECT * FROM ".$db_prefix."articlerate
                                            WHERE articleid='$articleid' AND userid='$pauserinfo[userid]'");


替换为:

$ipaddress = getip();
if ($pauserinfo[userid]!=0) {
        $checkvote = $DB->fetch_one_array("SELECT * FROM ".$db_prefix."articlerate
                                            WHERE articleid='$articleid' AND userid='$pauserinfo[userid]'");

} else {

                                            WHERE articleid='$articleid'
                                            AND ipaddress='".addslashes($ipaddress)."'");
}


查找:

$DB->query("INSERT INTO ".$db_prefix."articlerate (articleid,userid,vote,date,reason)
                   VALUES ('$articleid','$pauserinfo[userid]','$vote','".time()."','".addslashes(trim($_POST[reason]))."')");

替换为:
$DB->query("INSERT INTO ".$db_prefix."articlerate (articleid,userid,vote,date,reason,ipaddress)
