2.1 Config to 2.3.1, UI not allowing change
I've made a new 2.3.1 box and restored a config from my 2.1 box onto it, it all seems to work fine but the UI doesn't reflect any changes made.
I've tried adding and removing VLANs, enabling and disabling interface, and changing firewall rules, but when save is pressed the page reappears as the same and the changes haven't been applied.
ALso just UI specific things like adding widgets to the dashboard doesn't work.
The filesystem is mounted rw
Have you granted yourself the "privilege" deny config-write?
That will prevent any attempts at save from being effective.
e.g. this "not a bug" Redmine issue: https://redmine.pfsense.org/issues/6376
That was the issue! We're using LDAP groups for access, and the permission was added to these groups.
