Edit Post Link Not Showing on Posts

I realize there are similar topics, but I have tried ‘solutions’ and have no luck.

I’m using the ‘blankslate‘ theme; the Page edit post links show up fine, but the Post edit links don’t show.

The following code is on the page.php, but when put on the single.php, did nothing.
<?php edit_post_link( __( 'Edit', 'blankslate' ), '<span class="edit-link">', '</span>' ) ?>

This is the code on the single.php:

<?php if (is_single(array('bh-news','bh-events','bh-announcements'))): ?>
<?php get_header('behavioral'); ?>
<?php endif; ?>

<?php if (is_single(array('idd-upcoming-events','idd-advocacy-corner','idd-consumer-satisfaction-2','idd-volunteer-or-intern','idd-newsletters'))): ?>
<?php get_header('iddservices'); ?>
<?php endif; ?>

<?php if (!is_single(array('bh-news','bh-events','bh-announcements','idd-upcoming-events','idd-advocacy-corner','idd-consumer-satisfaction-2','idd-volunteer-or-intern','idd-newsletters'))): ?>
<?php get_header(); ?>
<?php endif; ?>

<article id="content">

<div id="largecol">
<?php the_post(); ?>

<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

<h1 class="columnheaders"><?php the_title(); ?></h1>

<div class="columntext">
<?php
if ( has_post_thumbnail() ) {
the_post_thumbnail();
}
?>
<?php the_content(); ?>

<?php wp_link_pages('before=<div class="page-link">' . __( 'Pages:', 'blankslate' ) . '&after=</div>') ?>

<?php edit_post_link( __( 'Edit', 'blankslate' ), '<span class="edit-link">', '</span>' ) ?>

</div>

</div>

</div></div>
</article>
<?php get_footer(); ?>

>> The web page to look at is this page

The small, right column is the post, the larger right column is the page.

And code to the page template that pulls in the posts:

<?php

/*

Template Name: Main Site Template

*/

?>

<?php get_header(); ?>

<div id="content">

<?php if (!is_page('programs-services')): ?>

<div id="maincol">

<?php the_post(); ?>

<div class="columntext">

<?php the_content(); ?>

<?php wp_link_pages('before=<div class="page-link">' . __( 'Pages:', 'blankslate' ) . '&after=</div>') ?>

<?php edit_post_link( __( 'Edit', 'blankslate' ), '<span class="edit-link">', '</span>' ) ?>
