I have run an upgrade on ispconfig 3 to version 18.104.22.168 which seemed to run perfectly fine.
But i have found a problem with roundcubemail.
before i upgraded it was verion .03 (i think) - well it worked fine before upgrade
I usually login via www.mywebsite.com/roundcube
after upgrade i could not log in, it had a login screen, when i typed email address and a password screen went to a white screen, and nothing.
i renamed /var/www/apps/roundcube to roundcube.old
went to system - packages and deleted roundcube.
then refreshed panel to reinstall roundcube again.
it seemed to reinstall fine, ssh in to check folder and new one was created.
under monitor - server had an error message
"Unable to connect to the databaseCan't create database 'ispapp1'; database exists"
I logged into phpmyadmin and renamed database, opened ssh terminal to server and ran "service httpd restart" went back in to phpmyadmin and it had created new database.
Now i have a new fresh looking login screen, but still cannnot login.
It now states "Invali server name"
