Hello,
Thanks for contacting us and we regret the inconvenience caused.
I checked your sitemap and I was able to replicate the error. Upon checking the source of the sitemap, I found that there is a blank line at the beginning. Please see the screenshot available in the sensitive data section of this ticket for a quick reference.
This issue is usually caused if there is a blank line/space in your website’s wp-config.php file or the theme’s functions.php file. You can remove that blank line/space to fix the issue.
Please refer to this tutorial guide for more details: https://rankmath.com/kb/fix-sitemap-issues/#blank-page
Let us know how that goes.
Thank you.
