URL File-Access is Disabled in the Server Configuration
If you've coded an "include file" into your php (perhaps php version 4?)...
<?php
include ("http://website.com/includes/header.php");
?>
/*Warning: include() [function.include]: URL file-access is disabled in the server configuration
in /home/YourUsername/public_html/index.php on line xx */
This is because in PHP 5 (or perhaps as part of a server security upgrade)
the allow_url_fopen is set to OFF... meaning absolute paths to other sites on the
internet aren't allowed.
The alternatives are:
RELATIVE PATHS
<?php
include (header.php); //include a file in the same directory
include (includes/header.php); //include a file from a directory under the PHP file
include (../header.php); //include a file from a directory above the current PHP file
?>
USING A TRUE "ABSOLUTE URL" FUNCTION
<?php
$File = file_get_contents("http://website.com/includes/header.php");
echo $File;
?>
SERVER VARIABLES
?php
include $_SERVER['DOCUMENT_ROOT'] . '/includes/header.php';
?>
//also note that some hosts have enabled "Options +Indexes"
(where a directory without an index.htm file is displayed as a list of files)
You SHOULD disable that listing using a .htaccess file (at the highest directory possible)
Options -Indexes
BECAUSE if you want to share things, then create a file to list them... but sharing
everything by default is a BIG security and privacy concern...
