Rest API is not working

Hello,

The REST API isn’t working. It was functioning properly before, but it suddenly stopped working in the last two days.

The following error is returned when I tested this URL – https://loveexpands.com/wp-json/contact-form-7/v1/contact-forms/1325248/feedback:

{"code":"rest_no_route","message":"No route was found matching the URL and request method.","data":{"status":404}}
