MailChimp Submit Error

When attempting to submit a MailChimp form on my site, the form becomes unclickable, no message is shown, and the console gives this error:

Uncaught TypeError: Cannot read property ‘error’ of null
at Object.success (main.js:88)
at i (jquery.js?ver=1.12.4:2)
at Object.fireWith [as resolveWith] (jquery.js?ver=1.12.4:2)
at y (jquery.js?ver=1.12.4:4)
at XMLHttpRequest.c (jquery.js?ver=1.12.4:4)

How do I fix this?

Hello There,

Thanks for writing in! Have you checked for any JS errors on the page? This could be caused by a 3rd party plugin. You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

If still the issue exists, would you mind providing us the url of your site so that we can take a closer look?

Regards.
