layout2 replaced classic-alt layout with 1.80

Kharis,
Thank you for your quick reply and detailed help. I followed your instructions, but unfortunately, it didn’t change the layout back to what it was so my app is no longer working. I left the page with your fixes so you could see what it’s doing. I’m getting a new error now:

Failed to load resource: the server responded with a status of 500 ()

When the layout is “layout2” (previously classic-alt), what should be displayed is a dropdown list of years, and underneath a list of show results. When the user selects a year, the list of show results changes to display the show result list that matches that year. Here’s the code from the page that is a modified copy in the sydney-child theme named archive-horse_show_results.php:

<?php
/**
 * The template for displaying archive pages.
 *
 * Learn more: http://codex.wordpress.org/Template_Hierarchy
 *
 * @package Sydney
 */

get_header(); 

$layout = sydney_blog_layout();

?>

	<?php do_action('sydney_before_content'); ?>

	<div id="primary" class="content-area col-md-9 <?php echo esc_attr( $layout ); ?>">

		<?php sydney_yoast_seo_breadcrumbs(); ?>

		<main id="main" class="post-wrap" role="main">

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

			<header class="page-header">
				<?php /**
					the_archive_title( '<h3 class="archive-title">', '</h3>' );
				 */?>
			</header><!-- .page-header -->

				<?php
				if ( $layout != 'layout2' ) {
						get_template_part( 'content',  get_post_format() );
					} else {
						
						get_template_part( 'content', 'horse_show_results' );
				}
 
				?>

		<?php endif; ?>

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

	<?php do_action('sydney_after_content'); ?>

<?php 
	if ( ( $layout == 'classic-alt' ) || ( $layout == 'classic' ) ) :
	get_sidebar();
	endif;
?>
<?php get_footer(); ?>

Thank you for taking another look at this.

Digging a bit deeper I found a new error, an unexpected end of file on: content-horse_show_results.php
