footer loads on all pages, but single.php

I am using the same footer.php on my index and single pages, but for some reason, the footer is not loading on the single.php pages. I have checked my single.php code several times and I think I have closed all the tags properly. Not quite sure what I did wrong. Here is the code for single.php…

<?php get_header('single'); ?>

    <section class="single_work_content">

        <?php query_posts($query_string . '&cat=-11'); ?>
        <?php
            // The Loop
            if (have_posts()): while(have_posts()): the_post();
        ?>

        <div class="row">
            <div class="single_breadcrumb large-12 column">
                <h3><a href="https://localhost:8888/public_html/view-my-work/"><span class="left_arrow">?</span> All Projects</a>
                <span>
                | <?php foreach((get_the_category()) as $category) { echo $category->cat_name . ''; } ?> |
                </span>
                    <?php the_title(); ?>
                </h3>
            </div>  <!-- End single_breadcrumb -->
        </div>  <!-- End row -->

        <?php the_content(); ?>

        <?php endwhile; endif; ?>

        <section class="other-posts">
            <div class="prev_post"><span id="prev_post_btn" ></span><?php previous_post_link('%link');?></div>
            <div class="next_post"><span class="next_post_btn"></span><?php next_post_link('%link');?></div>
        </section>  <!-- End oter-posts -->

    </section>  <!-- End single_work_content -->

<?php get_footer(); ?>

If anyone knows why this footer is not loading for single.php I would really appreciate the help!
