The problem is that the password you are trying to use to connect to the server is wrong, or you are attempting to use a password to connect to an account with no password (which, given that it's the root account, I sincerely hope not). Check your database. Yaml files to verify the correct password is being used.
Check any migrations you've written as well.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
