Parse error: syntax error, unexpected T_ELSE

I have this error message : Parse error: syntax error, unexpected T_ELSE in /www/htdocs/w00db417/index.php on line 33 – eventhough i had my backup restored for this file i don’t understand !

Here is the code :

<?php
/**
* The main template file.
*
* This is the most generic template file in a WordPress theme
* and one of the two required files for a theme (the other being style.css).
* It is used to display a page when nothing more specific matches a query.
* E.g., it puts together the home page when no home.php file exists.
* Learn more: http://codex.wordpress.org/Template_Hierarchy
*
* @package WordPress
* @subpackage Twenty_Eleven
*/

get_header(); ?>

<div id=”primary”>
<div id=”content” role=”main”>

<?php if ( have_posts() ) : ?>

<?php twentyeleven_content_nav( ‘nav-above’ ); ?>

<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>

<?php get_template_part( ‘content’, get_post_format() ); ?>

<?php endwhile; ?>

<?php twentyeleven_content_nav( ‘nav-below’ ); ?>

<?php else : ?>

<article id=”post-0″ class=”post no-results not-found”>
<header class=”entry-header”>
<h1 class=”entry-title”><?php _e( ‘Nothing Found’, ‘twentyeleven’ ); ?></h1>
</header><!– .entry-header –>

<div class=”entry-content”>
<p><?php _e( ‘Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post.’, ‘twentyeleven’ ); ?></p>
<?php get_search_form(); ?>
</div><!– .entry-content –>
</article><!– #post-0 –>

<?php endif; ?>

</div><!– #content –>
</div><!– #primary –>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Any clues what the problem is ?
