Note: As of WP-Members 3.0, you can add custom post types to the plugin’s main blocking options. See the options documentation section on Custom Post Types.
With explosion of custom post types in WordPress 3.0, the WordPress world has changed somewhat from what it was when WP-Members was first developed. If you have a theme or site that uses custom post types, you may find that you need to make some adjustments to accommodate what content you would like to be blocked.
