Hello @kodgems
Thanks for reaching out regarding your sitemap. This error usually occurs when there’s an empty whitespace or a blank line due to a conflict with another plugin or your theme. Usually, there is an empty space or a blank line before or after the closing PHP opening or closing tag, which shouldn’t be there.
You can narrow down the exact source of conflict by performing a conflict check. Once you have identified whether your theme or a plugin causes the issue, please contact the developers of that theme or plugin for assistance in finding and removing the white space.
Got it. I am using the DIVI theme and it is causing the issue. It automatically put a line space at the beginning of the page. I have to see and rectify the issue.
thank you for the quick support.
