❓ FAQ ✔ Where are my sitemaps?

Main index:

https://yoursite.com/sitemap.xml

Individual post types are linked from the index.

✔ Does this work with other SEO plugins?

Works technically, but you should avoid multiple sitemap generators.

✔ Why does “Bulk Check” redirect?

Because it uses secure admin-post.php actions to avoid WP’s “Cannot load {slug}” admin-page errors.
