Extension talk:Hierarchy/Hierarchy1.2.0.php

Any chance this version of the extension works with the followings versions:

MediaWiki 	1.16.0 PHP 	5.3.3 (apache2handler) MySQL 	5.1.51-log

I attempted to use the older version, but got the following error:

'''Detected bug in an extension! Hook fnHierarchySaveHook failed to return a value; should return true to continue hook processing or false to abort.'''

Any clue what may be causing this and/or do you think your newer version would correct it?

Thanks for any help you can give me.
