Anyone please help me active staking

Just make sure that your wallet is unlocked for staking and check the color of the diamond if it's blue than your staking is activated (check if your wallet is up-to-date).
it is black "staking is not active"

. I used V 3.0.0.13b
I need to do after unlock wallet

In my opinion it is important to import private key to new wallet and write 'staking=1' to diamond.conf. Staking with old wallet file was inactive for me too but maybe I was waiting too short.
