Kadence decides whether to show the featured image at the top of a post.

1. Go to Appearance → Customize → Single Posts (it may be called Posts or Blog, depending on your Kadence version) and look for the post layout settings.
2. Find the option to show the Featured Image and turn it on. You may see options for its position (above the title, or in the content) and its ratio or size.
3. Click Publish in the Customizer, then reload the article.
