Hi @samundra100, Seems like you have not selected any posts for main banner, please go through the Customizer > Main Banner and select categories or posts. If you would like to display latest posts try clearing the fields.
I could not find the Trending News section you are referring to can you send us an attachment at support@blazethemes.com.
As you can see, I have selected post category in both but it still doesn’t work. It was working perfectly few days ago. And same theme does works in my another website. Maybe this latest update has some issues.
