当论坛积分设置当中和板块设置当中对于上传附件没有设置积分策略的时候，版主删除含有附件的帖子可能
会出现程序错误。
解决方法，手工修改：
打开， include/post.func.php 查找：

function updateattachcredits($operator, $uidarray, $creditsarray) {
global $db, $tablepre, $discuz_uid;
$creditsadd1 = '';
if(is_array($creditsarray)) {
foreach($creditsarray as $id => $addcredits) {
$creditsadd1[] = "extcredits$id=extcredits$id$operator$addcredits*\$attachs";
}
}
$creditsadd1 = implode(', ', $creditsadd1);
foreach($uidarray as $uid => $attachs) {
eval("\$creditsadd2 = \"$creditsadd1\";");
$db->query("Update {$tablepre}members SET $creditsadd2 Where uid = $uid", 'UNBUFFERED');
}
}

将上述代码替换为

function updateattachcredits($operator, $uidarray, $creditsarray) {
global $db, $tablepre, $discuz_uid;
$creditsadd1 = array();
if(is_array($creditsarray)) {
foreach($creditsarray as $id => $addcredits) {
$creditsadd1[] = "extcredits$id=extcredits$id$operator$addcredits*\$attachs";
}
}

if(empty($creditsadd1)) return;

$creditsadd1 = implode(', ', $creditsadd1);
foreach($uidarray as $uid => $attachs) {
eval("\$creditsadd2 = \"$creditsadd1\";");
$db->query("Update {$tablepre}members SET $creditsadd2 Where uid = $uid", 'UNBUFFERED');
}
}
