PHP Fatal Error with WordPress below 5.8

PHP Fatal Error occurs when updating a user in WordPress below 5.8:

[25-Nov-2024 08:11:48 UTC] PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function SimpleWpMembership::sync_with_wp_profile(), 2 passed in /xx/wp-includes/class-wp-hook.php on line 287 and exactly 3 expected in /xx/wp-content/plugins/simple-membership/classes/class.simple-wp-membership.php:538

Reason is this change in WordPress 5.8 at profile_update action:

 * @since 5.8.0 The $userdata parameter was added.

Possible fix in file classes/class.simple-wp-membership.php line 538:

old:
public function sync_with_wp_profile($wp_user_id, $old_user_data, $userdata) {

new:
public function sync_with_wp_profile($wp_user_id, $old_user_data, $userdata = array()) {

Plugin data states compatibility “WordPress version 5.0 or higher”, this includes WordPress below 5.8.

Simple Membership 4.5.7, WordPress 5.6.14
