I just ran into this issue after upgrading from an earlier version of Revive. You have to pass a hostname as an additional parameter when you're calling the script from the command line. If you have this set up as a cron job, you need to change it there.
 
So, change this:
php /path/to/revive/maintenance/maintenance.php
 
To this:
php /path/to/revive/maintenance/maintenance.php localhost
 
There was apparently a bug in earlier versions that allowed you to call the script without the hostname parameter, which I didn't realize when I originally set up the cron. It was tricky to track down because there were no errors in debug.log.
