How to remove fresh posts (latest news) on the main page?

Solution to the problem. Very simple! Go to admin panel yoursite/wp-admin > Appearance > Theme Settings > Homepage Layout > The Layout Manager homepage > all Enabled to Disabled. Done! Now your Homepage is clean.

Here is a screenshot, I hope you understand. Have a nice day :)

From what I understand you want to remove the entire section outlined in red on your picture?

To do that, go into the admin > appearance > editor. Then on the right, find home.php and click it to edit the file.

Remove the following code from the file and click "Update File" to save...

<?php if ( !have_posts() ) : ?>
    <div class="alert">
        <?php esc_html_e( 'Sorry, no results were found.', 'virtue' ); ?>
    </div>
    <?php get_search_form(); 
endif; 

if( $summary == 'full' ){
    while (have_posts()) : the_post(); 
        get_template_part( 'templates/content', 'fullpost' ); 
    endwhile; 
} else {
    while (have_posts()) : the_post(); 
        get_template_part( 'templates/content', get_post_format() );
    endwhile; 
}

/**
* @hooked virtue_pagination - 10
*/
do_action( 'virtue_pagination' );
?>

Important Note

This will make an edit directly to your theme. A better way to do this is to make a CHILD THEME, then edit the file there. This will prevent you from losing any edits when your theme updates.
