已经将此出错信息详细记录, 由此给您带来的访问不便我们深感歉意



打开 source/class/block/group/block_groupattachment.php 文件
找到

$query = DB::query("SELECT attach.*,t.tid,t.author,t.authorid,t.subject $sqlfield
FROM `".DB::table('forum_attachment')."` attach
$sqljoin
INNER JOIN `".DB::table('forum_thread')."` t
ON `t`.`tid`=`attach`.`tid` AND `displayorder`>='0'
WHERE $htsql AND `attach`.`readperm`='0' AND `attach`.`price`='0'
$sql
$sqlban
$sqlgroupby
$orderbysql
LIMIT $startrow,$items;"
);

改为

 

   $query = DB::query("SELECT attach.*,t.tid,t.author,t.authorid,t.subject $sqlfield
    FROM `".DB::table('forum_attachment')."` attach
    INNER JOIN `".DB::table('forum_thread')."` t
    ON `t`.`tid`=`attach`.`tid` AND `displayorder`>='0'   
    $sqljoin
    WHERE $htsql AND `attach`.`readperm`='0' AND `attach`.`price`='0'
    $sql
    $sqlban
    $sqlgroupby
    $orderbysql
    LIMIT $startrow,$items;"
   );  
即可。
