Roundcube no longer works after upgrade of Linux from Ubuntu 14.04 to 16.04

I have Roundcube installed on a KVM virtual server which had previously been running Ubuntu 14.04, but since that
version was EOL in April, I upgraded to 16.04, and immediately discovered that Roundcube (1.1.3) no longer worked.
After the upgrade, I am able to login to the login page of Roundcube, but after that I get a blank white screen. A check
of /var/log/apache2 shows the following

Not a php programmer, so I'm not sure of what this is telling me... Prior to the Linux upgrade, Roundcube worked fine..

Time to upgrade Roundcube, you're currently trying to run a version from 2015. The error is do to a compatibility with PHP 7 that has been fixed in newer versions.
