before with the old wallet, when I unlocked for staking I could see the little diamond icon on the bottom right turning into a blue icon, now it says "staking is not active" with the version 3.0.1.0, do we need to add some new setting in the conf file to allow staking ?
Thats what happened to me, 1st i realise i was stuck on wrong chain was when my icon was no longer blue.
backup .dat do a full resync,
mine works fine now blue icon staking away
