When working with WordPress, displaying the featured image of a post is a common requirement. However, sometimes the featured image may not display as expected. This issue can be frustrating, especially when you're working on a project and need to troubleshoot the problem. In this article, we'll discuss the common issues that may cause the WP featured image not to display and provide solutions to resolve the problem.

Understanding the Issue

The issue of the WP featured image not displaying can be caused by various factors. Some of the common reasons include:

Incorrect image size: The featured image size may not be set correctly, which can cause it not to display.
Image not uploaded: The featured image may not have been uploaded correctly, or it may not be in the correct format.
Theme or plugin conflict: Conflicts with the theme or plugins can cause the featured image not to display.
Code issues: Issues with the code used to display the featured image can also cause the problem.

Code Used to Display Featured Image

The code used to display the featured image is typically located in the theme's template files. However, in this case, the code is being used outside of WordPress, which can make it more challenging to troubleshoot the issue.

define('WP_USE_THEMES', false);
require('blog/wp-blog-header.php');    
global $wpdb;

This code is used to include the WordPress blog header and make the WordPress database available globally. However, it does not include the necessary code to display the featured image.

Solutions to Resolve the Issue

To resolve the issue of the WP featured image not displaying, you can try the following solutions:

1. Check the Image Size

Instead of using custom code to display the featured image, you can use the WordPress function the_post_thumbnail() to display the image. This function is available in the WordPress API and can be used to display the featured image.

the_post_thumbnail();

This code will display the featured image of the current post.
