Button off, no action.

Hello!

I’m trying to implement the button on my search page. But the button appears gray without action.

Below I leave the code of the page in question with the implemented button. (it has some comments that I still need to remove..)

<?php
/**
 * Template Name: Search Page
 *
 * @package WordPress
 * @subpackage playboy-brasil
 *
*/
get_header();

global $query_string;

$query_args = explode("&", $query_string);
$search_query = array();

if( strlen($query_string) > 0 ) {
	foreach($query_args as $key => $string) {
		$query_split = explode("=", $string);
		$search_query[$query_split[0]] = urldecode($query_split[1]);
	} // foreach
} //if

$search = new WP_Query($search_query);
$results_count = $wp_query->found_posts;

?>

<main id="main" class="site-main search" role="main">
	<header class="compact">
		<div class="row spacer"></div>
		<div class="row">
			<div class="row center-xs white">
				<div class="container">
					<h2 class="col-xs-12">
						<?php echo $results_count; ?> RESULTADOS PARA:
					</h2>
				</div>
			</div>
			<div class="row center-xs white">
				<div class="container">
					<h1 class="col-xs-12">
						<?php the_search_query(); ?>
					</h1>
				</div>
			</div>
		</div>
	</header>
		<div class="corpo-geral busca">
	<?php // Start the loop.
		if( $search->have_posts() ):
			while( $search->have_posts() ) : $search->the_post();
				?>
				<?php include( locate_template( 'page-templates/content-posts-template-xxg.php' ) ); ?>
				<?php
			endwhile;
		endif;
		?>
	</div>
	<div class="row center-xs">
			<div class="col-md-4 col-xs-10">
				<!-- <a class="btn outline font-24" href="#">Carregar mais resultados</a> -->
                <!-- Ajax Load WordPress button -->
                <?php echo do_shortcode('[ajax_load_more post_type="post, page, portfolio" search="'. $search_query .'" orderby="date" posts_per_page="4" scroll="true" css_classes="plain-text" button_label="Carregar mais resultados"]');
                ?>
			</div>
		</div>
</main>

<?php //get_template_part('page-templates/content-top5'); ?>
<?php //get_template_part('page-templates/content-pbshop'); ?>

<?php
get_footer();
?>

I had made a button and it was working, but the staff who handled the writing of the website created a parent category that included several existing categories.

So before I had:

– cat1 > post, post, post
– cat2 > post, post, post
– cat3 > post, post, post
so on…

And now I have:

– parentcat1 > cat1 (with posts), cat2 (with posts), so on …

Any ideas?
Thanks in advance.
