Hi @vikasbendha,
Your blog listing template does not include any If blog_author statements, which are supposed to evaluate to True if you are looking at a blog author page. When you click on the More by this author link, the URL correctly shows the format of a blog author page (e.g. Certified to transform - Mindvalley Coach). However, the content of the page doesn’t get filtered to show the author’s posts because the HubL statement that filters by blog author is missing from your listing template.
Here is a link to our blog markup documentation for blog authors: Blog templates - HubSpot docs
