My installation is still showing warnings when I visit ssu_check.php

I am using the .htaccess file that is provided and this is my includes/configure.php setup:
PHP Code:
define('HTTP_SERVER', 'http://mysite.com');
define('HTTPS_SERVER', 'https://mysite.com');
define('DIR_WS_CATALOG', '/store/');
define('DIR_WS_HTTPS_CATALOG', '/store/');
and all of my cache files are set to 777
Can anyone explain why I'm getting these warnings? The don't make sense to me.
