At first you should check recommendation from exception: “Please verify that the current setting of session.save_path is correct (/var/lib/php/session) Array’ in”. Then check if the user (probably www-data) has permission to write into /var/lib/php/session/ .
Unfortunately, this error references a Zend Framework 1 library. ZF1 reached its end-of-life date on 2016-09-28. As such, we will typically close such questions, and direct users to Stack Overflow.
One note: the error you post above indicates that permissions were denied when trying to either read or create a session file, so the first stop is to determine if the web user has the ability to read and write in the session directory (which appeas to be /var/lib/php/session).
