Page template suddenly not displaying the_content() - php

Question

I've suddenly had an issue with a site I run.
Yesterday, the Business Page template on my site stopped showing the_content() copy. I updated 4 plugins earlier in the day; Contact Form 7, Yoast SEO, Jetpack and Wordfence Security. I can't 100% link these as the reason for the issue, because I never noticed the missing content. It was reported by a user. However I know the content was displaying 2 days ago, for sure.
Either way, I individually deactivated all my plugins, but the content didn't reappear.
Below is the code for the page template:
<?php
get_header();
// Calculate the best link back
$taxonomy = reset(wp_get_post_terms( get_the_ID(), 'business' ));
$back_link = get_term_link( $taxonomy, 'business' );
?>
<?php $sidebar_class = ''; ?>
<?php if($background_image = ardee('business_header')) { ?>
<div class="business-header" style="background-image: url(<?php echo $background_image; ?>);">
<?php } else { ?>
<?php $sidebar_class .= ' business-sidebar-flush'; ?>

<?php get_footer(); ?>
Anyone spot any glaring issues? I should stress that I didn't edit this in any way prior to the issue.
The content appears fine on all other templates, it is only this one that has the issue, but it's a very important page.

Answer 1

I think the issue is you used the_content(); without loop and without loop they can't get the content of page. Use below code and write your code in between them and then check.
<?php
while ( have_posts() ) : the_post();
// Write your code here
endwhile;
?>
