4. Edit dcsetup.php
This file contains parameters that DCForum+ requires to run. You won't need to edit most of them. Just to get it started, you'll only need to define the following variables in dcsetup.php
Database paramters - Ask your ISP what these values are
-------------------------------
DB_HOST - Typically "localhost" since most MySQL servers are on the same server as web server
DB_NAME - database name
DB_USERNAME - database username
DB_PASSWORD - database password
Forum parameters
--------------------------------
ROOT_URL - This is the URL to /dc directory...for example,
http://www.yourdomain.com/dc BACKUP_DIR - Location where backup file will be saved. This can wait until your forum is installed.
Open dcsetup.php file in your text editor and define these variables. Once you're done, upload dcsetup.php to your /dc directory.
