This only happens when WP_NEWSPACK_DEBUG is set to true.
This originally was discovered on the theme demo sites; it's been recreated on a Jurassic Ninja site, and a localhost test site as well.
To Reproduce
Steps to reproduce the behavior:
- Run the latest version of thew Newspack Plugin.
- Add
define( 'WP_NEWSPACK_DEBUG', true );to your wp-config.php
