I have integrated DUO with my WordPress site by following this guide. Everything works.
The only issue is that the default WordPress logo still shows on the DUO login screen.
I followed the WP official guide on replacing the logo with my logo. It works for the default login (i.e. http://www.mydomain.com/wp-login.php) but not on the DUO redirected auth screen. Please advise where to look.
