What is causing this error? jquery.php? version=1.3.2&gzip=0&farfuture=0:1

Question

I’m having trouble identifying this error that appears on one of the pages of a website:

Uncaught Syntaxerror: Unexpected Identifier jquery.php? version=1.3.2&gzip=0&farfuture=0:1

I’ve done some research and it seems to be related to Fututre Expire header, but I also think it may be that the Jquery version is outdated. The site was created through Joomla. If anyone can help me identify the problem, I’d be most grateful.

Here follows the jquery.php from which the error arose:

<?php
// no direct access
defined( '_JEXEC' ) or die( 'Restricted access' );

jimport( 'joomla.plugin.plugin' );

/**
* jQuery loading plugin
*
* @version      1.0
*/

//TODO: Create translation ini files

class plgSystemJquery extends JPlugin {

function plgSystemJquery(& $subject, $config) {
    parent::__construct($subject, $config);
}


function _getPath() {
    $mainframe =& JFactory::getApplication();

    $gzip = $this->params->get('gzip', 0);
    $farfuture = $this->params->get('farfuture', 0);
    $version = $this->params->get('version','1.3.2');

    $path = 'plugins/system/jquery/';

//      if (!$gzip && !$farfuture) {
 //         $file = 'jquery-'.$version.'.min.js';
 //     } else {
        $file = 'jquery.php?version='.$version.'&amp;gzip='.$gzip.'&amp;farfuture='.$farfuture;         
//      }
// Prepend ../ if we're in the backend
        if($mainframe->isAdmin()) {
        $path = '../'.$path;
    }

    return $path.$file;

}

function onAfterDispatch() {

    $doc =& JFactory::getDocument();

    if ($doc->getType() == 'html' && $this->params->get('bottomscript', 0) == 1) {
        $version = $this->params->get('version','1.3.2');
        $js = '<script type="text/javascript">if (typeof(jQuery) == "undefined" || (typeof(jQuery) != "undefined" && jQuery.fn.jquery != "'.$version.'") )
            document.write(unescape("%3Cscript src=\''.self::_getPath().' \' type=\'text/javascript\'%3E%3C/script%3E"));</script>';
        JResponse::appendBody($js);

        $js = '<script type="text/javascript">$jquery = jQuery.noConflict();</script>';
        JResponse::appendBody($js);

    }

    if ($doc->getType() == 'html' && $this->params->get('bottomscript', 0) == 0) {

        // Add jquery to the scripts
        $doc->addScript(self::_getPath());

        // Get head data
        $headdata = $doc->getHeadData();

        // Take the scripts part
        $scripts = $headdata['scripts'];

        // Reverse the array so we can pick jquery easily
        $revscripts = array_reverse($scripts,true);

        // Take the jquery field
        $keys = array_keys($revscripts);
        $key = $keys[0];
        $jqueryscript = $revscripts[$key];

        // Reconstruct the scripts array with jquery as first
        $newscripts[$key]  = $jqueryscript;
        foreach ($scripts as $path=>$type) {
            $newscripts[$path] = $type;
        }

        // Set the new head data
        $doc->setHeadData (array('scripts'=>$newscripts));

    }

}
