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/s...p-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
- Code: Select all
<?php the_post_thumbnail( $size, $attr ); ?>
But I can't get it working. Any help greatly appreciated
- Code: Select all
