Your welcome.tpl should look like this:

{* $Id: welcome.tpl,v 1.23.2.1 2005/04/23 08:32:48 max Exp $ *}
{if ($active_modules.Greet_Visitor ne "") and ($smarty.cookies.GreetingCookie ne "") and $logout_user eq ''}
<H3>{$lng.lbl_welcome_back}, {$smarty.cookies.GreetingCookie|replace:"\'":"'"} </H3> 
{else}
<H3>{$lng.lbl_welcome_to} { $config.Company.company_name }</H3>
{/if}
{$lng.txt_welcome}



{if $active_modules.Bestsellers ne "" and $config.Modules.bestsellers_menu ne "Y"}
{include file="modules/Bestsellers/bestsellers.tpl"}
{/if}



{include file="customer/main/featured.tpl" f_products=$f_products}

Make sure you didn't delete txt_welcome from the language variables section.
