Featured image is not uploading

Question

1. I click the set featured button
2. try to add image in set featured option
3. when I click set featured image button the image doesn't upload

I have already updated my theme and wordpress theme after this issue. Tested on different web browsers but issue is not getting resolved. What should I do?

Answer 1

1. Switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue.

2. Maybe a third party plugin causes a js conflict/error on the admin screen. Please try to deactivate all plugins and check if this solves the issue. If yes activate them one by one again to find the incompatible plugin.

Answer 2

Same issue happened with me when i was using below code in my js file in my plugin . This might help authors.

// Enable Media Upload 

if(function_exists( 'wp_enqueue_media' )){

    wp_enqueue_media();

}else{

    wp_enqueue_style('thickbox');

    wp_enqueue_script('media-upload');

    wp_enqueue_script('thickbox');

}
