Before you do anything, back up your wallet first.
Wait till your wallet full sync and go to setting tab - unlock wallet.
My master node is on vps but the wallet is not responding many times, sometime fatal error show up.
Now I'm stuck there lol. Thinking about create new vps.
So everything must be done on virtual machine?
ps: I don't have Otion "Unloc" only "Encrypt" or this is the same?
