Migrate wordpress server to localhost problems

I have not looked at the guide but chances are that it’s still looking for resources from the server URL. I would start by defining in your wp-config.php file the following:

define('WP_HOME', 'YOUR_LOCAL_SITE_ADDRESS');
define('WP_SITEURL', WP_HOME);

And then do a search/replace using a plugin finding all instances of your server address by your local address.

This plugin should help you:

!!! BACKUP the database before you do any replacements !!!
