There were no GUI changes between 1.3.3 and 1.4.0. Could you post the logs? And does it work again if you downgrade to 1.3.3?
The one with no GUI is when it upgrade from 1.2.5 to 1.4.0, worked fine after downgrade.
And now it complete the DB rebuilding, I change it to 1.4.0 then the GUI showed up.
I will try another unit do the upgrade with 1.4.0 to get the log.
