Reset default roles and capabilities

1 Views

I’ve been having a difficult time adding custom post type capabilities to roles (Adding capabilities to default roles) and I suspect that my muddling around may have caused some problems. I also have installed and de-installed various plugins some of which added capabilities. As a result My WP Role object is a bit of a mess. Does anyone know of a way to reset capabilities or do I need a fresh install?

  1. I use User Role Editor. You can delete added roles, and reset roles from the plugin page.

    To reset the administator role, you can, as of WP 3.4+, add

    define('URE_SHOW_ADMIN_ROLE', 1);

    to your wp-config.php file. After having done so, you need to go to Users > User Role Editor and click “Reset”.

  2. If you don’t want to install a plugin to just to do this one task, you can call the WordPress function directly to rebuild the roles and their capabilities.

    if ( !function_exists( 'populate_roles' ) ) {
  require_once( ABSPATH . 'wp-admin/includes/schema.php' );
}

populate_roles();

  3. I find an easier way to reset roles and their associated capabilities is to use wp-cli.

    wp-cli has a built-in method for resetting roles. You can specify any that you want to reset. For example:

    wp role reset author contributor editor subscriber

    There is also an --all flag, which you can use like this:

    wp role reset --all

    Warning that this will include resetting the administrator capabilities, which may remove access to some plugins, so use with caution.
