Wordpress' "nothing here"-page instead of RoundCube-setup

[elsebeth]

Hi there,

I installed Wordpress a while back on my Ubuntu server. I am able to use it from my own domain, so it seems to work just fine.

But as I am a complete novice here, I am unable to make both RoundCube and Wordpress work on the same domain.

As I installed Postfix, Dovecot, and RoundCube, and went to mail.domain.com/mail, I get the wordpress-error page "Nothing here".

How do I solve this, so I actually get the roundcube setup page and keep going.

I used this guide for wordpress: https://www.linuxbabe.com/ubuntu/install-wordpress-ubuntu-20-04-apache-mariadb-php7-4
I used this guide for postfix, dovecot, and roundcube: https://www.vultr.com/docs/how-to-install-postfix-dovecot-and-roundcube-on-ubuntu-20-04
