I tried this "walletpassphrase YOUR_PASSWORD 9999999 true" in console but says error. Also I Have not set any password as there is no conf file in there. What should I do in order to get minting
You and I have the same question
Hope someone can help us answer
Wish us luck

if you did not set a password then your wallet is not locked and you dont need to do that
if you dont understand semantics please use google
