I was suddenly logged out of my Grafana admin account and couldn't log in as it showed "Invalid username or password". Even though I entered the correct password.
I tried following instructions from https://community.grafana.com/t/admin-password-reset/19455/5 to update the password in my grafana.db file. First it showed the error that I was trying to edit a readonly database. Then when I changed the permissions, it is showing the error: enter image description here
Can you please let me know whats wrong and how can I log in again? If i re- install then all progress will be lost
