Blog layout

Hello
I’m using the “Elegant” blog style and want to achieve the same look as in your gym demo.
There are a few issues:

I chose to show the excerpts and a “read more” link,but the excerpts aren’t showing.
Nothing changes if I choose any of the other options either.. All there is is a “read more” button.

Another thing I want to change is the link to the author page when clicking on the image.
I would like the image to link to the post itself.
How can I achieve that?

Thank you
