Yes, the mysql show databases using:
mysql -u admin -p -e "show databases;"
and entering the root password, shows the roundcube database as one of the databases.
I have tried to change the db password using setprop and then changing the password of the roundcube user but that did not work either.
There is a slight change - when I load roundcube I get the page with the menu (mail, address book, calendar, settings) with a black top and grey body background. In the middle of the body the following message in a white box:
DATABASE ERROR: CONNECTION FAILED!
Unable to connect to the database!
Please contact your server-administrator.
In /opt/roundcube/logs/errors the following is shown in relation to this login attempt:
