My server has been running just fine for over a year, until I upgraded PostfixAdmin and somehow messed things up. Now I can't log in, and my mail client (Evolution, if it matters) keeps popping up an authentication request. The server is Ubuntu 20.04, my Dovecot is version 2.3.7.2, and Evolution is 3.40.4-1. I've also tried logging in with Roundcube with no success. Any insight or suggestions will be gratefully received!
Here's the most recent entry from /var/log/mail.err:
