How to Disable double line breaks with paragraph elements in WordPress?

The wpautop() function adds <p> and <br> tags to your content in order to preserve line breaks.

remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );

function aiooc_crunchify_wpautop_nobr( $content ) {
    return wpautop( $content, false );
}

add_filter( 'the_content', 'aiooc_crunchify_wpautop_nobr' );
add_filter( 'the_excerpt', 'aiooc_crunchify_wpautop_nobr' );
