Hi,
Sorry, but your answer makes no sense to me. (It must be my fault, for sure 😉 )

This is a screenshot of what I was referring to in your demo.

screenshot of demo

The top main menu option “blog” in your demo opens a page which shows three posts (Img, title and excerpt). I have a top menu, too. I have a “posts page” (where posts should show), and I have some posts. The problem is that mi “posts page”, the one I accede through the top menu, only shows the title of the posts.

I hope you understand what I mean
