I've moved my WordPress install, but now the site doesn't load properly

To fix this issue, open the wp-config.php file in the root of where WordPress is installed (normally httpdocs). Add the following lines beneath any existing 'define()' statement:

define('WP_SITEURL', 'http://' . $_SERVER['SERVER_NAME']);
define('WP_HOME', 'http://' . $_SERVER['SERVER_NAME']);

Your site should now load as normal. Once you've successfully loaded it, you can remove the last of these three define statements.

If you had WordPress HTTPS (SSL) plugin installed prior to the move, you will need to add this line as well:

define('WPHTTPS_RESET', true);
