解决办法 
cmsxx_archives 添加postcount int(10) UNSIGNED default 0 
然后打开plus\feedback.php 找到大约220左右 
//保存评论内容 
if($comtype == 'comments') 
{ 
$arctitle = addslashes($title); 
if($msg!='') 
{ 
$inquery = "INSERT INTO `cmsxx_feedback`(`aid`,`typeid`,`username`,`arctitle`,`ip`,`ischeck`,`dtime`, `mid`,`bad`,`good`,`ftype`,`face`,`msg`) 
VALUES ('$aid','$typeid','$username','$arctitle','$ip','$ischeck','$dtime', '{$cfg_ml->M_ID}','0','0','$feedbacktype','$face','$msg'); "; 
//插入位置1 
$rs = $dsql->ExecuteNoneQuery($inquery); 
if(!$rs) 
{ 
echo $dsql->GetError(); 
exit(); 
} 
//插入位置2 
插入位置1内容: 
$rowc = $dsql->GetOne("Select count(*) as count from `cmsxx_feedback` where aid ='$aid'"); 
$pcount = $rowc ['count']; 
$inquery2 = "update `cmsxx_archives` set postcount = '$pcount' where id = '$aid'"; 
插入位置2内容: 
$rs = $dsql->ExecuteNoneQuery($inquery2); 
if(!$rs) 
{ 
echo $dsql->GetError(); 
exit(); 
} 
只需要复制以上内容到你想调用的地方即可。
