Form won’t send – endless loading circle

Ther appears to be a CORS issue on your site. In the browser’s JS console I’m getting an XHR status 404 for https://mercedesdantes.com/wp-json/contact-form-7/v1/contact-forms/3414/feedback/. This is the JSON response:

Response { type: “cors”, url: “https://mercedesdantes.com/wp-json/contact-form-7/v1/contact-forms/3414/feedback/”, redirected: true, status: 404, ok: false, statusText: “”, headers: Headers(3), body: ReadableStream, bodyUsed: false }
index.js:1:7005

My NoScript browser plugin asks me to allow scripts from https://mercedesdantes.com as well as from https://mercedesdantes.com, so apparently somewhere you have a reference to the domain on an insecure protocol. It must be HTTPS everywhere.

This is the error in console

How I can solve this? My hosting setup https 7 years ago and I dont had any problem until this update. Contact form worked fine until now.

Thanks for the help!

Accessing https://mercedesdantes.com/wp-json/contact-form-7/v1/contact-forms/3414/feedback/ directly it shows us the JSON response. It seems to be a REST API issue. I’m not experienced enough with this API to give a solution but the response code “rest_no_route” gives us a hint. An internet search for “Wordpress rest_no_route” brings up a couple of results that might shed more light to this issue.

Thanks for the help, I searched but I cant found how to fix it. I trying deactiviting plugins and it works ok when Wp Rocket is off. I will try to roll back or wait until they fixed.
