I am trying to edit the footer of a theme I am using with WordPress. Nothing in the customization would help me achieve my goal, so I decided to edit the theme file itself. I could make the changes I wanted, but I cannot add a new line after the string (ALL RIGHTS RESERVED). I tried PHP_EOL and .”rn”. but to no avail.

Here is the code:

<?PHP
/**
 * Template part for displaying site info
 *
 * @package theme-name
 */

?>

<div class="site-info">
    <?php echo wp_kses_post( html_entity_decode( esc_html__( 'Copyright © ' , 
'theme-name' ) ) );
        echo esc_html( date( 'Y' ) );
        printf( esc_html__( ' MICHAEL GREEN. ALL RIGHTS RSESERVED by', 'theme-name' ) );
    ?>
    <a href="<?php echo esc_url( __( '//themes.com', 'theme-name' ) ); ?>" 
target="_blank">
        <?PHP
            printf( esc_html__( 'MICHAEL GREEN', 'theme-name' ) );
        ?>
    </a>
</div><!-- .site-info -->

How should I edit this file to have a new line after (ALL RIGHTS RESERVED)?
