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.
