Farmhouse - How to Setup Related Posts
The Farmhouse theme includes a Related Posts feature on every single post between your content and comments as shown below:
To add this, navigate to Settings > Related Posts and set the three sections as follows:
NOTE: If there is content in the CSS field, highlight and delete that content. Save changes.
If you need to rebuild the post links, you can select "rebuild" in this tab.
If the rebuilding/linking get's stuck and/or you receive an error message, navigate to the plugins directory, deactivate the plugin and then reactivate it. It will automatically open to the plugin settings where you can link the posts. You'll then want to Regenerate Thumbnails.
