Thanks for the super fast response.
I think you've identified the problem.
I didn't recognize the database credentials in wp-config.php
I've changed them to the existing database credentials.
The second WordPress instance now works but it's getting the data from the first WordPress instance.
Doesn't each WordPress instance needs it's own database?
I've tried to create a new database in 2 ways:
1. On the Database tab at http://localhost/phpmyadmin it says "Create database: No Privileges"
So I can't do it that way unless I can get "Privileges"?
2. Following the instructions (to the letter) at https://wiki.bitnami.com/Components/MySQL#How_to_create_a_database_for_a_custom_application.3f
I get as far as "flush privileges;" which gives an error.
When I enter "flush privileges;" it's no longer at the "mysql>" prompt but a new "->" prompt.
After entering "grant all privileges on test4.* TO 'user4'@'localhost' identified by 'new password' "
I get a new "->" prompt. Which is where I erroneously enter "flush privileges;" and get an error.
I must be missing something.
The mysql prompt instructions certainly seem to create new databases, as using the same database name again (e.g. test4) produces "ERROR 1007 (HY000): Can't create database 'test4'; database exists"
It's confusing that "bitnami-wordpress-4.0.1-0-module-windows-installer --wordpress_instance_name wordpress2" doesn't seem to create a new database and yet creates wp-config.php with the following:
I'm just looking at the help file from produced by "bitnami-wordpress-4.0.1-0-module-windows-installer --help" to see if it gives any further information.
Thanks again for any assistance.
