PHP page display problem - please help

[angelclawdust]

a little while ago our coder got a promotion in his job and was no longer able to help with are site.
unfortunately he also felt the need to stop the page loading and therefore breaking our site.
i have all the database files and every single file for the site reuploaded to a sub domain on my hosting account…
After months of scouring the code many times i cant for the life of me figure out what the problem is and where to start to fix it…
Iam also not brill on PHP myself but we cant find any1 to continue and fix it so ive been plodding along with it ripping my hair out lol as the only thing i can get to load on the page is the banner and the menu!!
im not sure what code to post here so what ill do is post a link to the site - and add the index.php code below - if anyone who wishes to help me start to figure this out i can happily add more code etc to better aide you…

site link is http://fifa-gaming.net23.net

index.php
[php]<?
include_once(‘header.php’);
$page = “homepage”;
?>

<? include_once('top_bar.php');?> <? //include_once('menu.php');?> <? include_once('divlefttop.php');?> <? include_once('divleftmiddle.php');?> <? include_once('divleftdown.php');?> <? include_once('divmiddletop.php');?> <? //include_once('divmiddlebestof5.php');?> <? include_once('div_middle_news.php');?> <? include_once('divmiddledown.php');?> <? include_once('smallleaguetablerighttop.php');?> <? include_once('divbanner.php');?> <? include_once('divvideo.php');?> <? //include_once('divrightdown.php');?>

<? include_once('footer.php'); ?>[/php]

Does anybody have a few suggestions as to why the remainder of the page wont load at all please??
any help big or small will be greatly appreciated

Are u sure that all included files exists, and what version of php are u using, i think verion 4 and 5 use <?php instead for <?.
