wpcf7.initForm is not a function

I got the same issue, as a result the form will not submit and throws and AJAX error (in my case an empty page is show) Code 400.

Unfortunately, I was not able to solve it, so I disabled the Plugin and added some custom code to my page
possible solution

If you find a solution, I still would like to know about it. ??

I saw the answer in the topic “Plugin Button is not trigger”

If you follow the solution of Ionwi. This solved the problem for me

To fix the issue I had to replace line 273 of woocommerce-quote-or-enquiry-contact-form-7.php:

wpcf7.initForm(jQuery('.wqoecf-pop-up-box .wpcf7 > form'));

replace with:

jQuery('.wqoecf-pop-up-box .wpcf7 > form').each(function() {
    wpcf7.init(jQuery(this)[0]);
});

You have to update first to version 1.9
