Hi, thanks for this excellent extension of publish press
The correct display of multiple authors in content view was astonishing!

However:
https://europadecentraal.nl/wp-admin/ppma-authors this page and the first item in the submenu of Authors in the admin menu does not work. It shows a 404 (at my site)

The links to the author pages do no longer work, but show a 404 instead
mysite.com/author/name

Is this a known issue or is there something wrong in my settings?
