My issue is that when I do a simple Admin Dashboard change, like updating a post or page, I sometimes wait up to 10 minutes for the request to finish. I have tried restarting the process and my server many times; the only way it works is if I wait all 10 minutes or so for the request to finish. Here is a screen shot of what the error looks like:

admin-ajax.php + load-scripts.php error

That error will loop 5-10 times, making it take forever to post anything. It looks like jQuery UI is causing all these issues when it is loaded via admin-ajax.php and load-scripts.php.

My setup is a bit convoluted because I'm trying to create a re-usable code-base for my projects. First of all, I am running it locally using Gulp and the connect-php server, but I also have MAMP Pro running for the database, which is doing MySQL replication to a BlueHost server for back-up.

I am using Timber and Advanced Custom Fields Pro for my custom theme. Then, I'm trying to strip as much Javascript that I don't need from WordPress as possible and I wire dependencies automatically with gulp, so my functions.php contains the following code:

add_filter( 'emoji_svg_url', '__return_false' );

function disable_wp_emojicons() {
  // all actions related to emojis
  remove_action( 'admin_print_styles', 'print_emoji_styles' );
  remove_action( 'wp_head', 'print_emoji_detection_script', 7 );
  remove_action( 'admin_print_scripts', 'print_emoji_detection_script' );
  remove_action( 'wp_print_styles', 'print_emoji_styles' );
  remove_filter( 'wp_mail', 'wp_staticize_emoji_for_email' );
  remove_filter( 'the_content_feed', 'wp_staticize_emoji' );
  remove_filter( 'comment_text_rss', 'wp_staticize_emoji' );

  // filter to remove TinyMCE emojis
  add_filter( 'tiny_mce_plugins', 'disable_emojicons_tinymce' );
add_action( 'init', 'disable_wp_emojicons' );

function disable_emojicons_tinymce( $plugins ) {
  if ( is_array( $plugins ) ) {
    return array_diff( $plugins, array( 'wpemoji' ) );
  } else {
    return array();
add_action('init', 'disable_emojicons_tinymce');

function kp_deregister_scripts(){
add_action('wp_footer', 'kp_deregister_scripts');
add_action('wp_header', 'kp_deregister_scripts');


function bower_enqueue_assets() {
  // bower:js
  wp_enqueue_script('jquery-js', get_stylesheet_directory_uri() . '/bower_components/jquery/dist/jquery.js');
  wp_enqueue_script('tether-js', get_stylesheet_directory_uri() . '/bower_components/tether/dist/js/tether.js');
  wp_enqueue_script('bootstrap-js', get_stylesheet_directory_uri() . '/bower_components/bootstrap/dist/js/bootstrap.js');
  wp_enqueue_script('ResizeSensor-min.js', get_stylesheet_directory_uri() . '/bower_components/resize-sensor/ResizeSensor.min.js');
  wp_enqueue_script('slick-js', get_stylesheet_directory_uri() . '/bower_components/slick-carousel/slick/slick.js');
  wp_enqueue_script('jquery-form-validator.min.js', get_stylesheet_directory_uri() . '/bower_components/jquery-form-validator/form-validator/jquery.form-validator.min.js');
  // endbower

add_action('wp_enqueue_scripts', 'bower_enqueue_assets');

function enqueue_recaptcha() {
  // Enqueue recaptcha script from Google
  wp_enqueue_script('recaptcha', 'https://www.google.com/recaptcha/api.js');

add_action('wp_enqueue_scripts', 'enqueue_recaptcha');

function contact_mailer() {
    // Custom mailer code here using PHPMailer

add_action('wp_ajax_contactmailer', 'contact_mailer');
add_action('wp_ajax_nopriv_contactmailer', 'contact_mailer');

function mailchimp_subscribe() {
  // Custom MailChimp subscription that just uses cURL

add_action('wp_ajax_mailchimpsignup', 'mailchimp_subscribe');
add_action('wp_ajax_nopriv_mailchimpsignup', 'mailchimp_subscribe');

On top of that, I have my own in-theme MailChimp and contact form mailer (using PHPMailer) code built-in.

I have also tried to use HeartBeat Control and I've set it up to only run on editing posts and slow it down to 60 seconds. That has intermittently worked in that this only happens one out of five or six posts now.

Anyways, I will try on a live server soon enough, but for now, this is really slowing things up on the development side and I'd like to get to a point where this isn't an issue. Anything else I can try?

  • Specifically the chunk of minimized code for(f in d)void 0!==d[f]&&g.setRequestHeader(f,d[f]+"");g.send(b.hasContent&&b.data||null) initiates the error. Jul 31, 2017 at 18:13
  • On a remote BlueHost VPS, it is much much faster. What can I do to improve my localhost/gulp hosting? Should I use MAMP, Vagrant, or a Docker? Aug 1, 2017 at 0:38
