Missing Featured Images
If you’re not seeing featured images displayed in your posts or featured posts sections, then you either 1) don’t have featured images turned on, or 2) you don’t have featured images set in your posts. Here’s how to fix this:
1. To turn on featured images, head to Appearance > Customize > Theme Settings > Content Archives. Check the box to display the featured image. Save!
2. Make sure you’re setting the featured images in your posts. From your Dashboard, click on Posts and click Edit to edit a blog post that isn’t displaying a featured image. On the right sidebar in the Document tab and under the Featured Image section, make sure you’ve set a featured image.
