Hello Stefano,
Apologies for the link above which probably didn’t shows the locked content when you looked at it. I had removed the locked content feature while debugging the problem. I was going to send you to a development environment but I discovered that that server isn’t sending the confirmation email so there would be no way for you to test it. So instead I’ve re-enabled the locked content extension and you can see it here:
https://mapre.lbl.gov/spatial-data/
and here:
https://mapre.lbl.gov/country/djibouti/
I’ve tested the process again to confirm that the problem persists.
Thank you so much for your help.
Ian
