 * Hello [@comsoft](https://wordpress.org/support/users/comsoft/),
 * Thanks for reaching out regarding your XML sitemap. We also received the error
   below when loading the sitemap:
 * _error on line 2 at column 10: XML declaration allowed only at the start of the
   document_
 * This is caused by an [empty whitespace or a blank line](https://yoa.st/3vp), 
   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](https://yoa.st/3vq).
   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.

   require any further assistance please create a new issue.
