 * When I open sitemap.xml I see validation problem:
 * This page contains the following errors: error on line 2 at column 6: XML declaration
   allowed only at the start of the document Below is a rendering of the page up
   to the first error.
 * Is it white space bug?

 * edit: problem solved. White space in functions.php

 * Hi [@enforces](https://wordpress.org/support/users/enforces/),
 * I’m glad you were able to find the cause of the issue.
 * As you found out, it’s a whitespace issue in any PHP file. We have an article
   on this here:
