Hello @NickMacedo,
Thanks for writing in!
You only added this HTML code into the page:
<script src="example.js" crossorigin="anonymous" referrerpolicy="no-referrer"></script><br />
<!-- Data output container --></p>
Be advised that you also need to upload the “example.js” file into your WordPress directory.
To get this issue resolved, you can do this:
1.) Download the Pro child theme here: https://theme.co/docs/child-themes
2.) Install and activate the Pro child theme.
3.) Log in to your FTP and browse to [your wordpress dreictory]/wp-content/themes/pro-child/js/ folder.
4.) Upload the example.js and script-filter-example.js JS files
5.) You will have to enqueue the JS files properly: https://www.wpbeginner.com/wp-tutorials/how-to-properly-add-javascripts-and-styles-in-wordpress/
6.) Or you can simply update your HTML and supply the DIRECT file path for example:
<script src="https://example.com/wp-content/themes/pro-child/js/example.js" crossorigin="anonymous" referrerpolicy="no-referrer"></script>
Best Regards.
