Remove sticky from post

Hi niustephanie

You can do that by creating child theme
1. After creating child theme successfully then go to main theme’s folder you will find index.php file.
2. Now copy and paste that file from main theme’s folder to child theme’s folder.
3. Now copy and paste below code in index.php file as a whole.

<?php
/**
 * The main template file.
 *
 * This is the most generic template file in a WordPress theme
 * and one of the two required files for a theme (the other being style.css).
 * It is used to display a page when nothing more specific matches a query.
 * E.g., it puts together the home page when no home.php file exists.

 * @package Intergalactic
 */

get_header(); ?>

	<div id="primary" class="content-area">
		<main id="main" class="site-main" role="main">

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

			<?php /* Start the Loop */
			$stickies = get_option('sticky_posts');
if( $stickies ) {
   $args = array( 'ignore_sticky_posts' => 1, 'post__not_in' => $stickies );
   global $wp_query;
   query_posts( array_merge($wp_query->query, $args) );
}?>

			<?php while ( have_posts() ) : the_post(); ?>

				<?php
					/* Include the Post-Format-specific template for the content.
					 * If you want to override this in a child theme, then include a file
					 * called content-___.php (where ___ is the Post Format name) and that will be used instead.
					 */
					get_template_part( 'content', 'home' );
				?>

			<?php endwhile; ?>

			<?php intergalactic_paging_nav(); ?>

		<?php else : ?>

			<?php get_template_part( 'content', 'none' ); ?>

		<?php endif; ?>

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

<?php get_footer(); ?>

4. Now Go to Admin Panel and activate child theme.
Note: Please customize files of child theme, so your changes will not overwrite on theme update.

Best Regards!!!
