Form Submission Gets Stuck on Processing

[ad_1]

Hello,

One of our clients uses ninja forms for their contact form and it seems to have been getting stuck on a form submittal.

I have an hunch that this is being caused by their Wordfence security plugin blocking the ajax request, but wanted to check in to see if this could be caused by any other known issue before I go mucking about in there.

Here is the console log upon submitting the form.

TypeError: Cannot read properties of undefined (reading 'nonce')
at n.submitErrors (submitError.js:12:1)
at p (backbone.min.js?ver=1691770341:2:3881)

at a (backbone.min.js?ver=1691770341:2:692)

The response from admin-ajax.php is missing as it says it is redirected.

Thank you for your help
