{“code”:”rest_cookie_invalid_nonce”, 403 when submitting form

Hi,

When upgrading your plugin from 4-6.1 to 5.11 version I only get this error when I trying to submit my form;

{“code”:”rest_cookie_invalid_nonce”,”message”:”Nonce f\u00f6r cookien \u00e4r ogiltig”,”data”:{“status”:403}}

See for example form at the bottom of;
