I am using Ubuntu 18.04-3 and when executing the command >
personal.unlockAccount(web3.eth.accounts[0],null)
I am getting the following error, enter image description here
I tried some of the suggestions here (enter link description here)
and the suggestions (here) for the internal/ethapi/api.go
I included in the file --allow-insecure-unlock (//I have add as in the suggestions but does not indicate where and how to place it//)
Appreciate your time in advance
