Hide 3 plugin menu items

Hi @dwnl

If you want to block a specific admin menu item, you can try this code:

add_action( 'admin_menu', 'members_remove_menu_pages' );
function members_remove_menu_pages() {
  $user = wp_get_current_user();
  if ( in_array('subscriber', $user->roles) ) {
    remove_menu_page('users.php');
  }
}

and replace ‘users.php’ part with your menu item.

Regarding hiding WooCommerce admin bar, have you tried to add this code that should prevent any user who cannot ‘edit_posts’ (subscribers, customers, etc) from seeing the admin bar:

function wc_disable_admin_bar( $show_admin_bar ) {
   if ( apply_filters( 'woocommerce_disable_admin_bar', get_option( 'woocommerce_lock_down_admin', 'yes' ) === 'yes' ) && ! ( current_user_can( 'edit_posts' ) || current_user_can( 'manage_woocommerce' ) ) ) {
      $show_admin_bar = false;
   }
 
   return $show_admin_bar;
}
add_filter( 'show_admin_bar', 'wc_disable_admin_bar', 10, 1 );

Kind regards
