/skin/common_files/single/home.tpl
contains the following
Code:
{elseif $main eq "product_options"}
{if $active_modules.Product_Options ne ""}
{include file="modules/Product_Options/global_prodopts.tpl"}
{/if}
First of all spelling error - prodopts I assume means products
Second - there is no such file in XC
This bug exists in all 4.6.x, not sure about earlier versions
