Since Latest update Observium no longer working

Hi Maurizio, we have not received the additional information requested earlier from you in this issue 'After latest update discovery.php returns an error the behavior of Observium is that it is no longer polling stuffs.

It seems that there is a problem with the DB but when updating ./discovery.php -u reports no error and has been issued immediately after svn update.

Here is the error in verbose mode:

SQL[SELECT * FROM `devices` WHERE `disabled` = 0 AND (`last_discovered` IS NULL OR `last_discovered` = '0000-00-00 00:00:00' OR `force_discovery` = '1') AND `poller_id` = '0' ORDER BY `last_discovered_timetaken` ASC]

SQL RUNTIME[0.00040293s]

SQL ERROR[Error in query: (Unknown column 'poller_id' in 'where clause') 1054]

#####  Finished discovery run at 2020-12-24 07:45:58  #####'!
