I have now updated to WP 4.8.1 and I still having the same problem… just to let u know 😉
I get the following error msg in the console when trying to submit a form:
POST http://[my_site]/wp-json/contact-form-7/v1/contact-forms/28/feedback jquery.js?ver=1.12.4:4 403 (Forbidden)
send @ jquery.js?ver=1.12.4:4
ajax @ jquery.js?ver=1.12.4:4
wpcf7.submit @ scripts.js?ver=4.9:335
(anonymous) @ scripts.js?ver=4.9:53
dispatch @ jquery.js?ver=1.12.4:3
r.handle @ jquery.js?ver=1.12.4:3
WordPress 4.7.5 and Contact Form 7 v4.9
The form has been working just fine but recently stopped to submit the form.
