Extension updated for beta 13.
I have fixed the URL not preserving the correct path when redirecting an admin page ("admin" would get removed from the URL).
It's not new, but after some investigation I confirmed the extension doesn't work with subfolder installs. The technical reason is that middlewares/base-path
prevents me from getting access to the full path, and I don't want to add additional logic to reconstruct the full URL. I have added a warning in the README.
