Thanks for super quick answer. However – the problem is that private_ID is not listed under Record Info tab.
The fields listed are: id (the successive post number), date_recorded, date_updated, last_accessed.
On a post in backend admin the fields listed are: id (the successive post number), private_ID (LH7OCI4S, set to length 8 with set_private_id_length) , date_recorded, date_updated, last_accessed.
Could there be a conflict between id and private_ID? However id cant be deleted.I have Participants Database Field Group Tabs but this seems to have no effect on the problem.
The field obviously is there and populated but is not displayed on Manage Database Fields page under the “Record Info” tab and is not include in CSV export. What to explore as next step? Best Regards / Kjell Nilsson
