WordPress Upgrade Causes Empty Page Template

After upgrading to 3.5.2 I am having a problem where the header and footer load on the page but my custom page templates are no longer working, they worked perfectly pre-upgrade so I am fairly certain this has to do with the upgrade to 3.5.2, has anyone else experienced this issue?

Here is the template code in case you can spot anything:

<?php
/*
Template Name : Grape Recipe Page Template
*/
?>
<?php get_header(); ?>
<article class="recipes">
    <header><h1><?php the_title(); ?></h1></header>
    <div id="recipe-navigation">
    	<h4>Show me recipes for:</h4>
		<?php get_sidebar('recipe-menu'); ?>
    </div>
    <section class="recipe-wrap">
		<?php
        // Query Recipes
		$temp = $wp_query;
		$wp_query = null;
		$wp_query = new WP_Query();
		$wp_query->query('showposts=5&post_type=fp_recipes&orderby=menu_order&order=ASC&recipes=Grape Recipes'.'&paged='.$paged);
		if($wp_query->have_posts()) : while ($wp_query->have_posts()) : $wp_query->the_post();
        ?>
        <div class="recipe group">
        	<div class="recipe-thumb float-left"><?php if(has_post_thumbnail()){the_post_thumbnail('recipe-thumb');} ?></div>
            <div class="recipe-copy float-right">
            	<h3><?php the_title(); ?></h3>
            	<ul class="recipe-details">
                	<li><?php if(get_field('serves')){echo 'Serves: '.get_field('serves');} ?>  </li>
                    <li><?php if(get_field('cooking_time')){echo 'Cooking Time: '.get_field('cooking_time');} ?>  </li>
                </ul>
                <h4 class="ingredients">Ingredients</h4>
				<?php the_content(); ?>
                <h4 class="directions">Directions</h4>
                <?php if(get_field('cooking_directions')){echo get_field('cooking_directions');} ?>
            </div>
        </div>
        <?php
		endwhile;
		if(function_exists('wp_paginate')){wp_paginate();}
		$wp_query = null;
		$wp_query = $temp;  // Reset
		else:
		?>
        <div class="recipe group no-posts"><p>Sorry, no recipes are available at this time.</p></div>
		<?php endif; ?>
    </section>
</article>
<?php get_footer(); ?>
