Reply To: Settings to show WP admin Bar on Front End

[Vladimir]

Yes, I missed a closing bracket at the line 8. Valid code is:

add_filter( 'woocommerce_disable_admin_bar', '_wc_disable_admin_bar', 10, 1 );
function _wc_disable_admin_bar( $disable ) {
 
    $user = wp_get_current_user();
    if ( !is_a( $user, 'WP_User') || !is_array( $user->roles ) ) {
        return $disable;
    }
    if ( !in_array( 'membership_manager', $user->roles ) ) {
        return $disable;
    }

    return false;
}

If filter does not help I suppose that another plugin may have own setting for showing admin bar at the front-end.

Try to add ‘manage_woocommerce’ to membership_manager role to exclude WooCommerce. Will it help? If it did not help, try to deactivate all plugins and re-test activating them back one by one, to isolate a source of the problem.
