Subtitle not displaying despite editing the template file

Hello,

Thanks for creating this plugin. I followed the instructions for editing the template page and edited my index.php (which is what seems to be the page that contains the code for my blog posts), however, the subtitles are NOT showing under the blog post title.

Here is the code (you’ll notice I put your piece of code in the middle where it “stands out”)

get_header(); ?>

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

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

			<?php /* Start the Loop */ ?>
			<?php while ( have_posts() ) : the_post(); ?>
<?php the_subtitle( '<p class="subtitle">', '</p>' ); ?>
				<?php get_template_part( 'content', get_post_format() ); ?>

			<?php endwhile; ?>

			<?php
			the_posts_pagination( array(
				'prev_text' => __( '&laquo; Previous', 'first' ),
				'next_text' => __( 'Next &raquo;', 'first' ),
			) );
			?>

Is this the right piece of code to put – and am I editing the right file?

Any help would be much appreciated!

Thanks,
Rahul
