littlebizzy / dashboard-cleanup Goto Github PK

Hi, I’ve just started testing WP with recently released PHP 8.1 and found that your plugin causes a fatal error:

PHP Fatal error:  Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class LittleBizzy\DashboardCleanup\Cleanup\Elements does not have a method "quickDraft" in \wp-includes\class-wp-hook.php:303
Stack trace:
#0 \wp-includes\class-wp-hook.php(327): WP_Hook->apply_filters(NULL, Array)
#1 \wp-includes\plugin.php(470): WP_Hook->do_action(Array)
#2 \wp-admin\admin.php(175): do_action('admin_init')
#3 \wp-admin\index.php(10): require_once('...')
#4 {main}
  thrown in \wp-includes\class-wp-hook.php on line 303

Hi, after switching my local WP to PHP 8 I see following in logs:

Warning: Private methods cannot be final as they are never overridden by other classes in \wp-content\plugins\dashboard-cleanup-1.1.2\helpers\boot.php on line 50

Warning: Private methods cannot be final as they are never overridden by other classes in \wp-content\plugins\dashboard-cleanup-1.1.2\helpers\singleton.php on line 76

I suppose switching
final private function __clone() {}
to
final protected function __clone() {}
should solve the issue
