Migrating WordPress Development Site

I am in the process of migrating a development WordPress site from my local machine/XAMPP to a domain that is fully hosted with Dreamhost. The domain is dev2.principledinnovation.com. Here are the steps I took:

  1. created a new database (pi_wp_2011) with a unique hostname (mysqldev2.principledinnovation.com) and assigned a user

  2. imported the local database into pi_wp_2011. the import was successful

  3. updated ‘wp_options’ and ‘home’ from http://localhost/wordpress to http://dev2.principledinnovation.com

  4. moved all files to dev2.principledinnovation.com

  5. updated my wp-config file:

define(‘DB_NAME’, ‘pi_wp_2011’);

/** MySQL database username */
define(‘DB_USER’, ‘username_here’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘password_here’);

/** MySQL hostname */
define(‘DB_HOST’, ‘mysqldev2.principledinnovtion.com’);

When I try to load the site at http://dev2.principledinnovation.com, nothing comes up. What have I missed?

Many thanks!
