How do I know what php version I have and MySql version to be able to upgrade?? EDIT: found the info on the cpanel on the left under general server information
I wish I did know the answer to that question - but i would highly recommend you email these guys: 21securityfaq@wordpress.org
I've got wordpress running on IIS and just now getting around to setting up a LAMP server in my house - so still learning all the uber security settings. I would assume for blocking access to files you just would chmod the permissions to them, but i'm at a loss as to blocking query strings.
