Hi, thanks. I just tried the beta.
There isn't a "rebuild sitemap" link, so all I did was remove the previous sitemap files and then save the plugin settings.
When I loaded the debug link, it showed everything correctly (custom tax pages too).
When I checked the sitemap url there was a sitemap there, filled with links to .xml files. When I followed those links, they each contained sitemaps for different sections of the site. Is this the intention?
One of my post types (generated by "The Event Calendar" plugin) has 150 posts, and there are 150 links for it in the sitemap, the first of which has the first post, the 2nd of which has the first 2 posts, the 3rd of which has the first 3 posts etc. - ie. the first post is linked to 150 times in the sitemap, the second posts is linked to 149 times etc. and it looks like this will increase every time I save a post.
