Hello Howard,
Thanks for writing in!
First of all, you have been editing the parent theme which is not the correct way when adding a customizations. Because what you are trying to accomplish requires a template customization, we would highly to suggest that you use a child theme. This allows you to make code changes that won’t be overwritten when an X update is released.
After your child theme is setup, please review how we recommend making template changes in Customization Best Practices.
Once you have your child theme active and ready, please follow the following steps below:
1] Using Notepad or TextEdit or Sublime Text or any text editor, please create a new file in your local machine.
2] Insert the following code into that new file
<?php
// =============================================================================
// VIEWS/INTEGRITY/TEMPLATE-LAYOUT-FULL-WIDTH.PHP
// -----------------------------------------------------------------------------
// Fullwidth page output for Integrity.
// =============================================================================
get_header();
?>
<div class="x-container max width offset">
<div class="x-main full" role="main">
<?php while ( have_posts() ) : the_post(); ?>
<?php x_get_view( 'integrity', 'content', 'page' ); ?>
<?php x_get_view( 'global', '_comments-template' ); ?>
<?php endwhile; ?>
</div>
</div>
<?php get_footer(); ?>
3] Save the file named as template-layout-full-payment.php
4] Upload this file to your server in the child theme's folder wp-content/themes/pro-child/framework/views/integrity
You will need to create the folder path since it does not exist in your child theme yet.
Hope this helps. Kindly let us know.
