I set wp-admin to be /secret/ and changed the wp-config.php file.
Plugin seems to working for most things, but using the update page or post gives a url of of https://mysite.com/secret/POST.PHP so it doesn’t update the page or post. Also, launching Beaver Builder from within the admin area on the back end also gives a URL not found.
