Hello,

I have tried to reproduce this issue, but it doesn’t show any error & it works fine. You can share your template code through Gist or Pastebin.

You can share your template code through Gist or Pastebin.

hmm..If I understand you correctly:
Any template of themes https://themes.trac.www.ads-software.com/browser/twentyfifteen/

I am confused.

In which file you inserted the shortcode?

1. Create a file in your theme root directory named “template-test.php” and paste the following code there.

<?php 

/**
 *
 *Template Name: Test Template
 *
 */
get_header(); ?>

<?php echo do_shortcode('[wpuf_form id="402"]'); ?>

<?php get_footer(); ?>

2. Create a page from admin and select the template “Test Template”
and publish it.

Now visit the page you created and you will see your form there.
