Catgegories Disappear from Sidebar after Object Cache activated

Hello. I activated the Object Cache on three blogs today with awesome performance results. The only problem I can see is that where there was a list of categories in the sidebar it now says “No Categories.”

You can see this on one of the three websites with broken categories:
http://celebrity.rightpundits.com/

The blog that still works without object caching enabled is this one:
http://sports.rightpundits.com/

The php call in the sidebar made by the Tiga theme is this:

<?php wp_list_cats(‘sort_column=name&optioncount=1’); ?>

</div>

The categories are all still there in the databases, and I optimized the tables.

The blogs are all on the same dedicated server, all using the same Tiga 1.0.2 theme on WordPress 2.1 on Linux.

The wp-config.php file now looks like this. I’ve been running wp-cache2.0.19 forever and just now added object caching which resulted in the problem:

<?php
/** WordPress’s config file **/
/** http://wordpress.org/ **/

// ** MySQL settings ** //
define(‘WP_CACHE’, true); //Added by WP-Cache Manager
define(‘DB_NAME’, ‘celebrity_rightpundits’); // The name of the database
define(‘DB_USER’, ‘xxxxxx’); // Your MySQL username
define(‘DB_PASSWORD’, ‘xxxxxx’); // …and password
define(‘DB_HOST’, ‘localhost’); // …and the server MySQL is running on

// Change the prefix if you want to have multiple blogs in a single database.

$table_prefix = ‘wp_’; // example: ‘wp_’ or ‘b2’ or ‘mylogin_’

// Change this to localize WordPress. A corresponding MO file for the
// chosen language must be installed to wp-includes/languages.
// For example, install de.mo to wp-includes/languages and set WPLANG to ‘de’
// to enable German language support.
define (‘WPLANG’, ”);

// Enable the WordPress Object Cache:
define(ENABLE_CACHE, true);

/* Stop editing */

$server = DB_HOST;
$loginsql = DB_USER;
$passsql = DB_PASSWORD;
$base = DB_NAME;

define(‘ABSPATH’, dirname(__FILE__).’/’);

// Get everything else
require_once(ABSPATH.’wp-settings.php’);
?>

Sorry if I am omitting details that are important. My level of technical ability is between bad and mediocre.

Any help appreciated.
