X-Cart forums - customize login box... please HELP!!

i checked my home.tpl thoroughly. however, i couldn't find any mistake on that about pairing the tags..
And.. as i mentioned, just same thing happened on the admin login page. so, i think it's not the problem of 'customer/home.tpl'.
please... help me.

just in case, here is my customer/home.tpl
Code:
{* $Id: home.tpl,v 1.67.2.8 2005/06/15 06:14:26 max Exp $ *}

{if $printable ne ''}

{include file="customer/home_printable.tpl"}

{else}

{config_load file="$skin_config"}

<HTML>

<HEAD>

<TITLE>

{if $config.SEO.page_title_format eq "A"}

{section name=position loop=$location}

{$location[position].0|escape}

{if not %position.last%} :: {/if}

{/section}

{else}

{section name=position loop=$location step=-1}

{$location[position].0|escape}

{if not %position.last%} :: {/if}
