Miniscript werkt niet naar behoren

Als luie beheerder gebruik ik een CMS: PHPFusion. Ondertussen probeer ik wel PHP te leren, en dat gaat mij vrij aardig af. Maar sommige dingen snap ik even niet, zoals deze.

Ik probeer een redelijk klein script op de site in te voegen, maar ik krijg de volgende foutmelding wanneer ik dit met behulp van error_reporting doe:

Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration in /home/vhosts/frisianpride.nl/httpdocs/themes/templates/panels.php(59) : eval()'d code on line 11

Warning: file_get_contents(http://voetbal4u.com/feed/) [function.file-get-contents]: failed to open stream: no suitable wrapper could be found in /home/vhosts/frisianpride.nl/httpdocs/themes/templates/panels.php(59) : eval()'d code on line 11

Daaruit neem ik op dat de panels.php niet juist is. Deze heb ik vervangen door de originele panels.php zoals die is geleverd door PHP Fusion. Bij een andere PHPFusion gebruiker werkt dit script wel, terwijl die dezelfde panels.php gebruikt...

Wie zou mij uit de brand kunnen helpen?

Panels.php ziet er als volgt uit:

<?php
if (!defined("IN_FUSION")) { header("Location: ../../index.php"); exit; }

// Calculate current true url
$script_url = explode("/", $_SERVER['PHP_SELF'].(FUSION_QUERY ? "?".FUSION_QUERY : ""));
$url_count = count($script_url);
$base_url_count = substr_count(BASEDIR, "/") + 1;
$start_page = "";
while ($base_url_count != 0) {
	$current = $url_count - $base_url_count;
	$start_page .= "/".$script_url[$current];
	$base_url_count--;
}
