Thumbnails on blog page not showing

Hi there,

I’m having an issue with the blog page on a couple sites I’m running the Evolve theme on.

The theme option to display posts’ featured images on the blog page works just fine, and it looks great on mobile devices, but the images turn out rather huge on desktops when using a one column blog page layout.

I would like to just display the thumbnails, as they would likely be smaller.

But the thing is, if, in the theme options, I choose not to display featured images and display the thumbnails images instead, no images show up on the blog page!

Any ideas?

Thanks in advance.
