Explain the Problem

Feeds are no longer updating since upgrading to PHP7.

I installed PHP 5.6 as discussed in issue #967 Since the PHP5.6 PPA was deprecated, I was forced to do an upgrade to 7.

In the log file I see this line: Fatal cron Failed to connect to the database: An exception occured in driver: could not find driver
