Doesn't poison Contact Form 7 emails, console errors, how to fix?

Question

WordPress

Sometimes the form on the site does not work, that is, when you click "Submit", errors appear in the browser console:
1. failed to load resource: the server responded with a status of 403 ()
2. failed to load /wp-json/contact -form-7/v1/contact-forms/638/feedback

But when you go to the admin panel and clear the cache (WP Fastest Cache), there are no problems with sending, but after a while errors appear again.

Who faced such a problem and how can it be solved?

Answer 1

From personal experience, I can only advise you to demolish this crap and create icons with a link in the form
a href="mailto:[email protected]">Here is the link text or image url /a
when clicked, the mail service or client will open and all the cases and don't worry with this crutch Then surprises await in the form of letters getting into spam
