RoundCube webmail is not accessible on Plesk: DATABASE ERROR: CONNECTION FAILED

    So after the update of about a week ago, my Roundcube on a fully upgrade Plesk Onyx on Ubuntu started showing an empty Inbox.
    After the latest update I hoped that would be fixed (but it wasn't).

    I've removed Roundcube and reinstalled it: still empty Inboxes.
    I then removed it again and noticed an error about /usr/lib/psa-roundcube folder not being removed because it wasn't empty.
    I then manually deleted the folder and reinstalled, which cause the database connection error mentioned in this article.

    I checked that the user was there and did everything is step 6.
    On Step 7 I keep getting an error that the roundcube database doesn't exist (and I've re-installed Roundcube multiple times and it always results in a message that the install was successful).

    I hope there's a fix for this, because I really dislike Horde.. :(

    Server details:
    OS:  Ubuntu 16.04.4 LTS
    Product:  Plesk Onyx - Web pro edition

    Step 6 refers to setting priveliges on roundcubemail which I have, but 7 refers to testing if roundcube exits, which I dont have. Does roundcube use 2 databases?

    Hello @Lars-Erik H.Bergland, 

    RoundCube uses one database. Step 6 is for creating the database user. Step 7 is for recreating RoundCube database in case it does not exist.
