when I type domainname.com/?author=1 I still see the author id of one slash user name.

It’s great that the users can’t show their usernames publically. But can you make it so the username doesn’t even show up in the “Display name publicly as” dropdown?

Activated the plugin but I can still see the author url

<?php the_author_posts_link(); ?>

Still shows the username.
