LFS Forum - PHP PHPbb buffs I need help!

Hey I don't know if this is the right section as it is only remotely related to LFS I thought it would be best to post here.

I'm having a little problem with my website after consulting afew people who couldn't find the problem I thought I would ask you guys as alot of you know your stuff.

Heres my problem. On my main website http://www.fibracing.co.uk I have a script to get the latest 5 forum topics made, that works perfectly but for some reason everytime a page is loaded its causing the forum to end its current session and log you out. I've tried everything I can think of and I just cant seem to find any solution.

Here is the code:

The following code is used above all the meta tags etc... I have removed quotes to save the post from being huge lol

<?php

$phpbb_root_path = 'forum/';

define ('IN_PHPBB', true);

if (!file_exists($phpbb_root_path . 'extension.inc'))
{
    die ('<tt><b>phpBB Fetch All:</b>
        $phpbb_root_path is wrong and does not point to your forum.</tt>');
}

include_once ($phpbb_root_path . 'extension.inc');

include_once ($phpbb_root_path . 'common.' . $phpEx);

include_once ($phpbb_root_path . 'includes/bbcode.' . $phpEx);

include_once ($phpbb_root_path . 'mods/phpbb_fetch_all/common.' . $phpEx);

include_once ($phpbb_root_path . 'mods/phpbb_fetch_all/posts.' . $phpEx);

$userdata = session_pagestart($user_ip, PAGE_INDEX);
init_userprefs($userdata);

$news = phpbb_fetch_posts();

phpbb_disconnect();

// echo ('<pre>'); print_r($news); die();

?>

And this is the code used to echo out the posts in the page body:

<table>

<td width="33%">

    <strong><a href="<?php echo append_sid($phpbb_root_path . 'viewtopic.php?t=' . $news[0]['topic_id']); ?>" target="_blank"><?php echo $news[0]['topic_title']; ?></a></strong>

Sorry if this is massive lol I'm just dying for a solution its been a problem ive been trying to solve without scrapping the script for many days now. I haven't been into webdesign all that long so its probably something simple I have overlooked.

Any replys would be great!
Thanks in advance,
Dale.
