clickable header problem for a newbie

i have the nebula-10 thyme installed and i have with a load of luck changed the header but i can’t make it clickable any help .
i have a wp-blog-header.php but it only says <?php

if (! isset($wp_did_header)):
if ( !file_exists( dirname(__FILE__) . ‘/wp-config.php’) ) {
if ( strstr( $_SERVER[‘PHP_SELF’], ‘wp-admin’) ) $path = ”;
else $path = ‘wp-admin/’;
die(“There doesn’t seem to be a wp-config.php file. I need this before we can get started. Need more help? We got it. You can create a wp-config.php file through a web interface, but this doesn’t work for all server setups. The safest way is to manually create the file.”);
}

$wp_did_header = true;

require_once( dirname(__FILE__) . ‘/wp-config.php’);

wp();
gzip_compression();

require_once(ABSPATH . WPINC . ‘/template-loader.php’);

endif;
