Hi Netzha,
when the Trigger is listed in the list of locked elements it cannot be modified by enabling/disabling via Admin UI (at least not permanently).
If you are running on Unix-like OS, then the node.ndf needs to be writable by the user your are using to start the IntegrationServer (rw-rw-r-- rights when doing a ‘ls -la’ in the ns///-directory.
If these rights are not met the tirgger should show as “system locked” in the overview of locked elenents.
Are there any messages in the server-log when trying to enable the trigger indicating some issues with the concurreny mode or the doc type being subscribed by the trigger?
Regards,
Holger
