It may possible after rebuilding the sitemap using Google XML Sitemaps plugin for your wordpress blog when you try to access sitemap.xml in your browser you may get following error.

Error loading stylesheet: An unknown error has occurred (805303f4)
http://www.domain.com/blog/wp-content/plugins/google-sitemap-generator/sitemap.xsl

just go to your Sitemap-core.php file located on following location in your FTP

/wp-content/plugins/google-sitemap-generator/sitemap-core.php

Edit it

function GetDefaultStyle() {
$p = $this->GetPluginPath();
if(file_exists($p . "sitemap.xsl")) {
$url = $this->GetPluginUrl();
//If called over the admin area using HTTPS, the stylesheet would also be https url, even if the blog frontend is not.
if(substr(get_bloginfo('url'),0,5) !="https" && substr($url,0,5)=="https") $url="http" . substr($url,5);
return $url . 'sitemap.xsl';
}
return '';

}

Replace it with following one

function GetDefaultStyle() {
/*$p = $this->GetPluginPath();
if(file_exists($p . “sitemap.xsl”)) {
$url = $this->GetPluginUrl();
//If called over the admin area using HTTPS, the stylesheet would also be https url, even if the blog frontend is not.
if(substr(get_bloginfo(‘url’),0,5) !=”https” && substr($url,0,5)==”https”) $url=”http” . substr($url,5);
return $url . ‘sitemap.xsl’;
}
return ”; edited by javadotnet.in*/

$p = $this->GetPluginPath();
if(file_exists($p . “sitemap.xsl”)) {
return ‘/wp-content/plugins/google-sitemap-generator/sitemap.xsl’;
}
return ”;
}
