解决在列表页调用副栏目，但列表页文章不显示方法：
打开 /include/taglib/arclist.lib.php，原代码如下：
if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')';
else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')';
将其替换成如下代码：
if($CrossID=='')
$orwheres[] = " (arc.typeid in (".GetSonIds($typeid).") or arc.typeid2 in (".GetSonIds($typeid).") or CONCAT( ',', arc.typeid2, ',' ) LIKE '%,".$typeid.",%' )";
else
$orwheres[] = " (arc.typeid in (".GetSonIds($typeid).",".$CrossID.") or arc.typeid2 in (".GetSonIds($typeid).",".$CrossID.") or CONCAT( ',', arc.typeid2, ',' ) LIKE '%,".$typeid.",%')";
