Featured Image thumbnail embedded in post (help with backticks?)

My blog is https://www.thegeekiary.com

I just switched over from wordpress.com to godaddy and am now using a www.remarpro.com theme. For some reason this theme makes all the featured images show up on the left hand side in the posts on the left hand side.

Also I’m not sure what a “backtick” is but from googling it looks like it’s a tilda? I put it after the ? on the first line and before the ? on the last line. If I didn’t use them correctly, can someone please help me know how to use backticks so I can show you the code I have?

This is the code from single.php which, from what I’ve googled, is the place that I need to go to remove this.

<? ~ php global $theme; get_header(); ?>

    <div id="main">

        <?php $theme->hook('main_before'); ?>

        <div id="content">

            <?php $theme->hook('content_before'); ?>

            <?php
                if (have_posts()) : while (have_posts()) : the_post();
                    /**
                     * Find the post formatting for the single post (full post view) in the post-single.php file
                     */
                    get_template_part('post', 'single');
                endwhile;

                else :
                    get_template_part('post', 'noresults');
                endif;
            ?>

            <?php $theme->hook('content_after'); ?>

        </div><!-- #content -->

        <?php get_sidebars(); ?>

        <?php $theme->hook('main_after'); ?>

    </div><!-- #main -->

<?php get_footer(); ~?>

[Backticks are the non-shift tilde key – above the tab key – or just use the CODE buttons – code above fixed]
