Error from menu builder

The menu builder plugin is very convenient and functional, but I receive the following warning:

WARNING: Deprecated in 2.3: Event [pagesetup, system] is deprecated. Use menu or page shell hooks. Called from [#9] /path/to/vendor/elgg/elgg/engine/classes/Elgg/EventsService.php:64<br /> -> [#8] /path/to/vendor/elgg/elgg/engine/lib/elgglib.php:551<br /> -> [#7] /path/to/mod/menu_builder/start.php:2

Please advise

Thanks
