MailChimp is a great solution to add the subscription form to our websites. The only problem is that the MailChimp Subscriber Pop-Up doesn’t work on WordPress websites. I added the MailChimp Subscriber Pop-Up embed code to one of my WordPress websites, but nothing happened when I loaded any website page where the pop-up should have appeared. I searched Google and noticed that many others have the same issue in WordPress.

Example of the MailChimp Subscriber Pop-Up embed code:

<script type="text/javascript" src="//" data-dojo-config="usePlainJson: true, isDebug: false"></script>
<script type="text/javascript">require(["mojo/signup-forms/Loader"], function(L) { L.start({"baseUrl":"","uuid":"xxxxxxxxxxxxxxxxxxxxxxxxxx","lid":"xxxxxxxxxxx"}) })</script>

What causes this problem

By analyzing the output code of the page I noticed that the MailChimp Subscriber Pop-up embed code (file at // tries to load the jquery.js file from the root directory of the website. But in WordPress, the jquery.js file located in the /wp-includes/js/jquery/ directory.

How to fix it

In order to get it work we need to add the jquery.js file to the root directory of the website. We will create file with the jquery.js name, but the content will be loaded from the jquery.js file that supplied with WordPress. Now, step by step.

Step 1. Design your MailChimp Subscriber Pop-up and copy the MailChimp Subscriber Pop-up embed code that will be offered to you.

Step 2. In WordPress Admin Panel install and activate the Head and Footer Scripts Inserter plugin.

Step 3. In WordPress Admin Panel go to plugin settings page (Settings -> Head and Footer Scripts Inserter). Paste the code (that you got on step 2) to the bottom field of this page, and click on the Save Changes button.

Step 4. Create an empty plain text file with the name jquery.js on your computer. Open it in the text editor and paste the following code into it:

jQuery.getScript("/wp-includes/js/jquery/jquery.js").done(function(){ });

Note: If you have the Mac computer then just use the “TextEdit” app that ships with every MacOS in order to create this file.

Step 5. Using FTP or your cPanel File Manager move the jquery.js file (that you created on step 4) to the root directory of your website. Usually the root directory is a directory with name www if you use cPanel, or httpdocs if you use Parallels Plesk Panel.

Done! Now, when you load any page on your website, your MailChimp subscribe pop-up should work.

Note: The MailChimp stores a cookie for one year to prevent you from seeing a pop-up repeatedly after you’ve closed it or filled it in. Don’t fall into the trap of thinking that the pop-up doesn’t work when it actually does. If you’re testing this you may need to clear cookies, use a different browser, or open a private browser window to see the form on repeat visits after dismissing or filling it.
