On clicking the New Product button, the resulting new product page simply displays as a blank white screen (and trying to add a new order manually also generates a similar result). There appear to be no errors happening at the server side but the browser’s JavaScript console shows a 403 permissions error when trying to retrieve
http://<server address>/wp-json/wp/v2/types/ppec-products?context=edit&_locale=user
(the caller is – api-fetch.min.js?ver=bc0029ca2c943aec5311)
Currently running WP 6.1.1 on Apache 2.4.29 running PHP 7.4.30 and MySQL 5.7.40-0 – all file system permissions show as writeable. Behaviour is consistent across Chrome, Safari and MS Edge browsers.
Can anyone who may have encountered this issue before suggest a solution? Thanks!
