I am installing WordPress on Windows Server with the DB in SQL Server. I've followed the instructions for installing wordpress and the DB Abstraction plugin but when I get to step 3: on this url
http://wordpress.org/extend/plugins/wordpress-database-abstraction/installation/
I get the message in my browser: Your wordpress install is missing the WP Db Abstraction plugin in the mu-plugins directory needed to access the database.
I've confirmed the wp-db-abstraction.php is in the wp_content\mu_pligins folder. I've copied the db.php file to the wp_content folder. I've also given the IIS user write permission on the directory.
My directory structure is as follow. C:\inetpub\wwwroot\blogs\wp-content\mu_plugins\wp-db-abstraction.
Has anyone run into this problem? I'm sure I'm following the instructions correctly.
I've downloaded WP 3.2.1 and WP DB abstraction plugin 1.1.1. And used the web platform installer to install pre-requisites. (Our MS SQL DB will be in a server farm.)
