Force Reindex of Processes
Sometimes the Magento indexes can get stuck in a "processing" state. If you have access to a shell, you can force a reindex. This will also show you success/failure messages for each index as it is rebuilt.
# cd into site root and do: php shell/indexer.php reindexall
If that doesn’t work, try deleting all the lock files in /var/locks and setting the permissions of the folder to 777.
