There should be a whole list of directories there and each should say Scanned xx files. I'm wondering if any files are listed though or if it's only the directories with Scanned xx files listed there.
If there are no files listed there, and you are using a totally default style (not the normal one), then you should also disable your plugins and then see if you still have this issue.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php
PHP Code:
define('DISABLE_HOOKS', true);
