进入后台--风格界面模版总管理---分页模版(page_index)---界面风格-->template.html(0)

找到：

<div>主题：<a href="dispbbs.asp?boardid={information/@lastpost_7}&amp;ID={information/@lastpost_6}&amp;replyID={information/@lastpost_1}&amp;skin=1"><xsl:value-of select="information/@lastpost_3" disable-output-escaping="yes" /></a></div>
    <div>发贴：<a href="dispuser.asp?id={information/@lastpost_5}"><xsl:value-of select="information/@lastpost_0"/></a></div>
    <div>日期：<xsl:value-of select="information/@lastpost_2"/><a href="Dispbbs.asp?boardid={information/@lastpost_7}&amp;ID={information/@lastpost_6}&amp;replyID={information/@lastpost_1}&amp;skin=1" title="主题：{information/@lastpost_3}"><img border="0" src="Skins/Default/lastpost.gif" alt=""/></a></div>

把1改为0就行了，0为平板（分页） 1为树型 2为平板
