select p.comments, a.action_id, a.active from POLICY_ACTION_LIST a INNER JOIN event_policy p ON a.rule_id = p.rule_id;

A query to activate them all should be just this:

update policy_action_list set active = 1;

Note that netxms server should be stopped before running any update queries to the DB.

I couldn't upgrade the server, there were many errors in the upgrading process so I had to make it this way.

In overall it's better to upgrade just with the same database - new server will upgrade it's structure. Installing a new system and migrating config approach is used not so often, while perfectly valid.

select rule_id, flags, comments from event_policy where rule_id in (59, 78);

See rule 60 is not working while rule 79 is working. Strange.
I also see a new row in the notification log.
There is no rule with "stop event processiong" checkbox.

What about Server Action Execution and Notification logs, is there anything there related to the email?
