Hi! we see blog posts are not included in sitemap? Is any way to fix that via RichBlog? or maybe we can change somewhere this set to include blog posts in sitemap?
The Rich Blog does not add this ability as it is a Core functionality and should be part of the Blog functionality in nopCommerce.
The nopCommerce team has added ability to add the Blog posts to the sitemap in nopCommerce 4.30 (still not released at the time of writing) - you can see the github issue
