On my 0.2.0 delegate node when I click on 'Stop Forging' button it asks for a password, entering my delegate passphrase there gives me 'Access denied' error ? I'm not able to stop my delegate and update it to 0.3.0 version.
Please help.
Go to your server, stop the 0.2.0a program / process, copy the blockchain over to the 0.3.0 folder, go to the 0.3.0 folder, mod the config.json text file with your forging account password, and start the 0.3.0 program/process.
Don't worry about gracefully doing a controlled transfer between the two versions. Just kill the old job and start the new job.
