Hello, This is my first post on the forum and I'm super glad that I found it! hopefully you can help me. I am trying to edit a wordpress plugin (https://github.com/samsonw/wp-grid-archives). It is an archive plugin that displays post title and excerpt sorted by date. I want to get it to display the post thumbnail or featured image. I posted the code I think i need to be changing at the bottom. I tried various things like placing <?php the_post_thumbnail( $size, $attr ); ?> But I can't work it out. Thank you very much for any help. It will be greatly appreciated!
