Make sure your newest PHP version is running.
Sometimes when you check PHP version using php -v it shows the latest installed version but the older one in running.
If you installed a new version of PHP, just remove older versions:
apt purge php7.0 php7.0-common
Having same issue, after checking lots of thing, my problem solved by removing older version.
