And

Deprecated: Return type of
NewfoldLabs|WP|Module\Installer\Models\PriorityQueue::compare($priority1, $priority2) should
either be compatible with SplPriorityQueue::compare (mixed $priority1, mixed $priority2): int, or
the #[ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in
/app/wordpress/content/plugins/bluehost-wordpress-plugin/vendor/newfold-labs/wp-module-
installer/includes/Models/PriorityQueue.php on line 16
