@shmoo I was debugging something similar yesterday. First, when you to go the tag sitemap, is it an empty page or blank page? That’s your first step.

This link will help you. For me, I had a empty page. I turned on wp_debug and there was a php error there. I fixed that, and unchecked the sitemap option, saved it, and rechecked it and saved it and it fixed the issue.
It was strange — the php error was only triggered on my posts sitemap. All the others worked fine.
Good luck!

Thanks,
When I try to reach the Tags sitemap -page generated by Yoast I’ll get a 404 not found error page.
Just did some troubleshooting and found out that this error was caused by not having any tags defined to my posts. This means, if you’re not going to use the tags feature inside WordPress the SEO plugin still creates a Tags_sitemap while I think it should just not generate a Tags_sitemap at all. Only generate sitemaps is you have some value in a taxonomy or post type.
