I apologize everyone, I missed an edit required in skin1/customer/home_main.tpl (this is a mod that has evolved over a few weeks, so I forgot about an initial edit)
Open skin1/customer/home_main.tpl:
Find:
Code:
{else}
{include file="common_templates.tpl"}
{/if}
Add before:
Code:
{elseif $main eq "sitemap"}
{include file="sitemap.tpl"}
