Resolution
-
Connect to the Plesk server via SSH.
-
Create the missing logfiles manually and assign required ownership for them:
# touch /var/log/maillog && chmod 640 /var/log/maillog
# mkdir /var/log/psa-horde && touch /var/log/psa-horde/psa-horde.log && chown horde_sysuser:horde_sysgroup /var/log/psa-horde/psa-horde.log
# touch /var/log/plesk-roundcube/errors && chown roundcube_sysuser:roundcube_sysgroup /var/log/plesk-roundcube/errors && chmod 640 /var/log/plesk-roundcube/errors
# touch /var/log/secure && chmod 600 /var/log/secure
