1) I was trying to switch to the Xml Sitemaps feature of WPSeo Yoast Plugin and yesterday everything seemed to work fine except for the author sitemap.
Right now I'm getting a 404 error when i point to the index and to all the other sitemaps. http://www.meridianionline.org/sitemap_index.xml
What's happened? And why the author sitemap wasn't working even when the others did.
2) After the last update I'm struggling with the OpenGraph that was working just fine before retrieving my post image and showing the thumb in Facebook. Right now I get like 15/20 images when sharing a link and none of them is the post featured image...
Any help guys?
Thanks in advance
