I wrote a plugin which adds additional functionality to Advanced Custom fields and the tinyMCE editor. All in all simple stuff with a bunch of js and css primarily.

Issue is that WP not only looks for the file in:


where it's actually located, but also:


Not only does it not look for the js file in the 'assets' folder, but it also looks for it in 'acf-field-column' folder, not 'acf-field-columns' (notice the 's' in columns). I'm using a child theme of GeneratePress.

I'm only enqueuing the files in the plugin master file, and only once

Heres my enqueue

// Add styles and js init
function acf_admin_enqueue() {
global $post;

if($post->post_type != 'acf-field-group'):

    // enqueue jquery UI script
    wp_enqueue_script( 'jquery-ui', plugin_dir_url(__FILE__) . 'assets/js/jquery-ui.min.js', array('jquery'), '1.0.0', true );

    // enqueue plugin jQuery
    wp_enqueue_script( 'pagebuilder-js', plugin_dir_url(__FILE__) . 'assets/js/input.js', array('jquery'), '1.0.0', true );

    // enqueue stylesheet
    wp_enqueue_style( 'pagebuilder-styles', plugin_dir_url(__FILE__) . 'assets/css/input.css', array(), '1.0.0', false);

// hook in styles and js
add_action('acf/input/admin_head', 'acf_admin_enqueue');

I have no folder called 'resources' in my child theme, thats only in the generatepress parent theme. Any ideas on what is going on here?

  • not sure if it is related by your handler names are very generic (jquery-ui especially very aweful) I would guess you have a collision of handler names that cause confusion Commented Jun 2, 2017 at 9:28
  • Just found the issue in one of the plugin files. It was just me not looking thoroughly enough. But thanks for the input. I should definitely change that handle. Thanks! Commented Jun 2, 2017 at 11:02

I'm a total dummy. Looked through the field file and found this:

function input_admin_enqueue_scripts()
    // Note: This function can be removed if not used

    // register acf scripts
    wp_register_script('acf-input-column', $this->settings['dir'] . 'js/input.js', array('acf-input'), $this->settings['version']);
    wp_register_style('acf-input-column', $this->settings['dir'] . 'css/input.css', array('acf-input'), $this->settings['version']);

    // scripts

    // styles


$settings->['dir'] was set to: get_template_directory_uri() . '/resources/acf-field-column/'

So that's where the 404 files got included.
