Bug fix for Sitemap Generator for WordPress 3.0b6

Clicking “rebuild the sitemap manually” link in the WP 2.1 admin panel generates a blank page in Firefox 2 and IR6.

The fix is to replace line 2331 of sitemap.php:

header(“location: ” . $this->GetBackLink());

by the following:

// Start gamedujour.com patch
if (!headers_sent())
{
header('Location: https://' . $_SERVER['HTTP_HOST'] . $this->GetBackLink());
}
else
{
echo '<script type="text/javascript">';
echo 'window.location.href="https://' . $_SERVER['HTTP_HOST'] . $this->GetBackLink() . '";';
echo '</script>';
echo '<noscript>';
echo '<meta http-equiv="refresh" content="0;url=https://' . $_SERVER['HTTP_HOST'] . $this->GetBackLink() . '" />';
echo '</noscript>';
}
// End gamdedujour.com patch
