page_content_custom tag not appearing in regions

I've got perch_content_create() in the template as well as perch_content_custom() - will this cause an issue?

Is there any other reason why this couldn't be working? I've got the html file _page_content.html in the relevant folder too. It was previously working until only recently where the template wasn't altered in any way.

<?php include($_SERVER['DOCUMENT_ROOT'].'/inc/header.php'); ?>
<?php
    perch_content_create('page content', array(
        'template'=>'_page_content.html',
    )); 
?>

<?php 
$page_title = perch_pages_title(true);
PerchSystem::set_var('page-title',$page_title); 
perch_content_create('page banner', array(
    'template' => '_page_banner.html',
)); 
?>
<?php perch_content_custom('page banner', array(
   'template' => '_page_banner.html',
)); 
?>

<main>
  <div class="content-wrapper">
    <div class="left-col">

        <?php perch_content_custom('sidebar widgets', array(
   'template' => '_sidebar_widgets.html',
)); 
?>


    </div>
    <!-- /div.left-col -->

    <div class="right-col">
     <?php perch_pages_breadcrumbs(); ?>
        <?php
    perch_content_custom('page content', array(
        'template'=>'_page_content.html',
    )); 
?>

    </div>
    <!-- /div.right-col --> 

  </div>
  <!-- /div.content-wrapper --> 
</main>
<?php include($_SERVER['DOCUMENT_ROOT'].'/inc/footer.php'); ?>

Sorry for the delayed response! This is what I get when debug is turned on for a page where the content regions aren't appearing...

Hi Drew,

I actually managed to fix this issue by creating a new template, which worked fine as the pages I was trying to create needed to be slightly different anyway. I believe the issue could have been that only a limited amount of pages were able to use one template.

Regardless, everything is working fine now - thanks for your help!
