@pinarpink I can update the access logged as admin. When I am logged as any other user including VIP user with all priviledges, I can't edit access - I am getting blank box with Edit access definition written in it.
Log:

dear @vildead I have committed a fix for this permission bug. It was not to do with the page logic, but with the data loader, which did not associate dataset permissions with local custodians.

In order to verify we have two options. Either go to the permissions view page and then save ( no changes necessary). Or drop the database and load_demo_data again. cheers
