Topic: Upgrade 14.04 to 16.04 on iredmail - One problem..
I upgraded my iredmail server from Ubuntu 14.04 to 16.04, and followed the
https://docs.iredmail.org/upgrade.ubunt … 16.04.html document on things to
fix/change to allow iredmail to operate under 16.04. All went well EXCEPT for
Roundcube showing the login screen, but after logging into a valid mail account
I get the dreaded white-screen of death.. Not sure where to go to troubleshoot
