Spinning icon, POST /wp-admin/admin-ajax.php 400 Error

    CentOS 7
    Wordpress 5.4
    Contact Form 7
    PHP 7.3.16

    Contact Forms don’t provide feedback, they simply show the spinning icon upon submission. Some simple forms generate an email. Others do not. No feedback is ever provided.

    When the simple test form above is submitted, I see something like this in the log (a successful submission and then a series of submissions with a 400 response from the server).

    I was able to get more information about the 400 POST error. This was due to some old JavaScript that tried to update a cart in the theme, which was no longer active. I’ve disabled that and we no longer see the error. However, I still only see the spinning loading icon, no response.

    In which form on the linked page do you see the problem?

    Sorry; I eventually removed the Contact Form 7 form and used a different plugin, which resolved the problem.
