Pure PHP Upload extension use the long predefined array variables ($HTTP_*_VARS), which usually are disabled in PHP 5.

To fix the problem place the following code before those of Pure PHP Upload:

<?php
if( !isset( $HTTP_SERVER_VARS ) )
{
$HTTP_SERVER_VARS = $_SERVER;
}
if( !isset( $HTTP_GET_VARS ) )
{
$HTTP_GET_VARS = $_GET;
}
if( !isset( $HTTP_POST_VARS ) )
{
$HTTP_POST_VARS = $_POST;
}
if( !isset( $HTTP_POST_FILES ) )
{
$HTTP_POST_FILES = $_FILES;
}
?>

The problem also can be fixed if you enable the long predefined array variables in your php.ini file.
To do that you have set register_long_arrays variable to On in your php.ini file.

register_long_arrays = On

Enable Debug Information:

If this does not fix the problem, enable the output of debug information which could be used for resolving the issue. To enable the debug information set $DMX_debug variable to true.

$DMX_debug = true

The resulting code may look like this:

<?php
$DMX_debug = true;

if( !isset( $HTTP_SERVER_VARS ) )
{
    $HTTP_SERVER_VARS = $_SERVER;
}
if( !isset( $HTTP_GET_VARS ) )
{
    $HTTP_GET_VARS = $_GET;
}
if( !isset( $HTTP_POST_VARS ) )
{
    $HTTP_POST_VARS = $_POST;
}
if( !isset( $HTTP_POST_FILES ) )
{
    $HTTP_POST_FILES = $_FILES;
}
?>
<?php
// Pure PHP Upload 2.1.3
if (isset($HTTP_GET_VARS['GP_upload'])) {
