Wordpress host IP changed

I've got a Wordpress site on our home intranet that has run into trouble now that the IP address has changed - The index page loads, but not the CSS and I can't log in to the site administration panel.

Unfortunately I am a bit behind on backups. Is there a way to get Wordpress to refer to the new IP address?

You have two places to update this (well three, but we'll stick with the two).

If you can still log into your admin section, type the following for your URI /wp-admin/options.php - so for example, if your site is http://localhost then your full URL will be http://localhost/wp-admin/options.php. Once you've logged into your site you should see two Fields (well you'll see a lot of fields), but you'll want to look for the two with URL's in them - the Site URL and the Blog URL (in WP 2.7 the fields are labeled "home" and "siteurl", not sure on the other versions).

Or, you can log into MySQL database and run the following.

Select * from wp_options where option_name = 'siteurl' OR option_name = 'home'; 

I just ran this today on one of my installs. If you're option_value is set to your localhost - you can then run the following:

update wp_options set option_value='' where option_name = 'siteurl';
update wp_options set option_value='' where option_name = 'home';

This should update your table structure.
