Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
This sitemap error indicates that there must be some white space before the XML Sitemap’s source code. You can check the source code of Sitemap to see if there are some extra blank lines before the XML. This is usually caused by blank lines or spaces in your wp-config.php or functions.php file.
Please check the link below and follow this troubleshooting guide to fix that issue:

Let us know how it goes. Looking forward to helping you.
Thank you.
