How to remove area under comments?

Have a look at the comments.php template.
You should be able to find the code that generates both of these and remove it.

I would normally encourage you to make a child theme first, but it looks like this theme has been heavily customized already… I might be wrong though.

I’m just now learning and, if I were to be honest, don’t even know anything about child themes. I assume that’s a theme that’s created from another theme, but with changes?
I pulled open the comments.php and looked through it (pasted below), but didn’t see anything recognizable (I was control Finding the word ‘feed’, for example.)
One thing I’ve been wondering in general is how to find where something is located within a theme when you want to remove it. Using Firefox’s editor, I can at least see what the code I need is sometimes, but not what file it’s in.
Still learning, like I said. ^_^ Sorry if I seem ignorant.

<?php // Do not delete these lines
	if ('comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Please do not load this page directly. Thanks!');

	if (!empty($post->post_password)) { // if there's a password
		if ($_COOKIE['wp-postpass_' . COOKIEHASH] != $post->post_password) {  // and it doesn't match the cookie
			?>

			<p class="nocomments">This post is password protected. Enter the password to view comments.</p>

			<?php
			return;
		}
	}

	/* This variable is for alternating comment background */
	$oddcomment = 'class="alt" ';
?>

<!-- You can start editing here. -->

<?php if ($comments) : ?>

	<div id="comments">
		<h2><?php comments_number('No Responses', 'One Response', '% Responses' );?> to “<?php the_title(); ?>”</h2>
		<ol class="commentlist">
			<?php foreach ($comments as $comment) : ?>
			<li id="comment-<?php comment_ID() ?>">
            <?php echo get_avatar( $comment, 35 ); ?>
				<h3><?php comment_author_link() ?> said:</h3>
				<small><a>" title=""><?php comment_date('M d, y') ?> at <?php comment_time() ?></a></small>
				<?php if ($comment->comment_approved == '0') : ?>
					<small><em>Your comment is awaiting moderation.</em></small>
				<?php endif; ?>
				<?php comment_text() ?>

			<?php endforeach; /* end for each comment */ ?>

	</div>

	<hr />

<?php endif; ?>

you seem to have changed the theme to ‘picoclean’ where for instance the ‘comments closed’ line is in comments.php:
<p class="nocomments"><?php _e('Comments closed', 'picoclean')?>.</p>

in the ‘amerifecta’ theme, the code for the comments related output is in page.php

Thanks! Yeah, I may have gotten sick of the inflexibility of the Amerifecta theme and found another to work for me. The only downside of my Picoclean one is that there’s no Widgetized footer, and the only included widgetized area in a single sidebar. Guess that’s the next thing I’ll have to figure out…
