BuddyPress.org

Here is single.php…

Here is Page.php
<?php
/**
* @package WordPress
* @subpackage Constructor
*/
wp_enqueue_script( 'comment-reply' );

// load header.php
get_header();

// load one of layout pages (layouts/*.php) based on settings
get_constructor_layout('page');

// load footer.php
get_footer();

Here is index.php…

Where should I look next and what should I change?

Thanks for your help.
Cheers
Roy
