Pls help me by explaining what I should fill in here....
I have created a database and add a user and it seems am getting it wrong

Pls explain well
Mqsql

Database name:

Database username:

Database password:

Database host:

Administrator details:
Admin username:

Admin password:

Admin mail:

Have you installed any CMS on your server ?
Because it will be easier to import those settings.

Database name is nothing but the name of the database you created.
Database username and password are credentials of the user that you added for that database.

As per your error, your database username password is wrong.
Make sure you have assigned the new user to the database that you created.
