Hi
Maybe some plugin that blocks access to API REST look this post: https://contactform7.com/2017/06/01/contact-form-7-48/#more-22829
“Contact Form 7 4.8 and later versions no longer use the jQuery Form Plugin (jquery.form.js) for Ajax form submissions.”
Hi
Problem with REST API if use plugin Shield Security by IControl (or similar plugin security) in Shield dashboard config – off “lockdown” (Disable) The Anonymous Rest API System. All works fine.
