I have a live site (example.com). Instead of making changes and finding bugs when the public can view the site, I decided to setup a staging webiste. I followed the directions for setting it up here.
It appears to have worked, when I go to staging.example.com everything is there. But when I try to login staging.example.com/wp-admin.php it keeps giving
ERROR: Invalid username. Lost your password?
I tried my normal password and the password I used to create the new database.
What did I do wrong or what step did I miss? How can I add a new user to the staging account? I checked wp-config.php and believe I have the DB_NAME, DB_USER and DB_PASSWORD correct.

staging.example.com/wp-admin.php
This path does not exist, you need go to
staging.example.com/wp-admin/
When you need to create new user with database - you can open the database with phpMyadmin, and create user in the table wp_users. The password field must be left blank, and then go to the wp-login.php and recover the password to setup new one.
