make header display on single blog page

Hello all,

I have three test pages . Home , ABout , Blog . All display the page header when clicked on. On my home page I’m using display-posts-listing plugin to display 2 blog posts. All good. However, when I click on one of these blog posts, to see the single full blog post, I don’t get the header displayed, but just the primary menu. How do I make this single display the header as well ?

Thanks

Neil.
