I have tested an upgrade from 2017.2 to 2018.2. Everything is fine exept that when I tried to change somethings in a custom web site from /AdaxesConfig I get a Access is denied when I validate the change.
I am logged into the new web console with the same user I use to change web interface in version 2017.2
I restored all web sites from the backup but not the services.
Thanks for you help.
