I'm looking for all blogs as public ... but even adding in the permissions, it keeps returning 404 error

Below is how I put it

// *1* OSSN allowed core pages
                    // only first part of url will be checked
                    array(
                        'css',
                        'js',
                        'action',
                        'administrator',
                        'uservalidate',
                        'resetlogin',
                        'index',
                        'login',
                        'avatar',
                        'userverified',
                        'two_factor_login',
                        'captcha',
                        'rsvp',
                        'contact',
                        'blog',
                    ),
                    // *2* be more specific: 'part1/part2' of url must match
                    // make sure part1 is not listed in the array above!
                    // in this example the footer links 'About' and 'Terms' are shown, while 'Privacy' needs logging in
                    array(
                        'site/about',
                        'site/terms',
                        'rsvp',
                        'contact',
                        'blog',

does anyone know how to help me? I've done cache cleaning and everything
