// if you block/redirect/restrict wp-admin this plugin does not work.
// this does not apply to block htaccess

// I do not assume any responsibility

// wp-postratings change this:
'ajax_url' => admin_url('admin-ajax.php', (is_ssl() ? 'https' : 'http')),
// to
'ajax_url' => site_url('admin-ajax.php', (is_ssl() ? 'https' : 'http')),

//________________________//

// wp-admin-ajax.php //

// copy wp-admin-ajax.php and paste to root site
//do not delete wp-admin-ajax.php from wp-admin folder

//change this:

require_once('wp-load.php' );

require_once( ABSPATH . '/wp-admin/includes/admin.php' );

require_once( ABSPATH . '/wp-admin/includes/ajax-actions.php' );

let me know.
