I have a site that was migrated a week ago from Movable Type 4 to WordPress and ever since then, the posts are not getting indexed into Google News. We used the same meta key that we used on MT4 and we did not change the domain name in the migration. We did, obviously, change to pointer to our multi-site WP installation on a new server.
We are using the Yoast plugin for all of our sites on the new WP server. Another site that was migrated shortly before this one is being successfully scooped up by Google. I removed any static sitemap files that might have been kicking around (I did that today) since the one site that is in Google news has no static sitemaps. Is it possible Google found a conflict between the static sitemap that was brought over on the migration and Yoast plugin. I get an error in Google webmaster tools that it looks like my Yoast sitemap is an html file. But I don't have control over it do I? And it's identical to the one that works.
This one works and is indexed by Google News
This one doesn't work and isn't indexed, but it used to be when it was in Movable Type.
Anyway ideas on what I can try next?
