I'm using the latest WP SEO and NextGen. I was hoping to get the NextGen images added to the sitemap.
First of all, the generated sitemap is dated as 1970-01-01.
Second, I see all ngg tags listed, but, all of them have 0 files in sitemap. But, when I click on some of them, it opens the ngg_tag/taqgname page, but for some tags no images are found, and for some wrong ones are found. I have not seen a properly generated ngg_tag page.
What is wrong and how do I fix it?
