Is there a possibility to override the core file at the URL
I added the file to the newly created folder
application/authentication/concrete but it didn’t work. I also added following line to
config/app.php without success:
'/login/concrete/password_sent' => '<my_theme>',
config/app.php the login page targets already
With c5-8 I could add the file
invalid_token with success (didn’t try this file on c5-9).
