Okay, finally got it all back up an running, however now have a strange problem.
With the image default factory reloaded, I log into the GUI as user admin p/w admin, when I go to System Config > Quick Start and click VLan tab
I get enter user and password, however admin admin does not work, the same happens when I go to Access Control > User Management and click Local Admins tab.
Loads of other tabs also have the same result
Is there a different default SuperUser Login and password for the GUI to access these settings ?
I created super user via console with privilege level 15 but sill get the same result.
That hit the nail on the head!
Last time I visited this system was 2015.
Would be grateful if you could provide the patch.
