Since the major update and after The Yoast plugin function Sitemap will not work, even after the latest update from Nextgen Gallery, it gave
b[c] += ( window.postMessage && request ? ' ' : ' no-' ) + cs;
------------------------------------------------------^
that is what yoast sitemap shows. If I disable nextgen gallery plugin the sitemap from Yoast works fine. But if I enable it, it will give the same :
b[c] += ( window.postMessage && request ? ' ' : ' no-' ) + cs;
------------------------------------------------------^
