Need to add some code but do not know where

[Diablotic]

I was also given this instructions:

In includes/class_bootstrap.php after:

$templater = vB_Template::create("footer");

add

ob_start();  
include("prolink.php");  
prolink_getLinks();  
$prolink = ob_get_clean();  
$templater->register("prolink", $prolink);

And in footer add:

{vb:raw prolink}

It appears to work only on my main page but it does not work on any of the thread pages nor forum lists.

Does this code look OK?
