Rebranding - Admin help content issue

Having an issue when uploading admin-help-content.php via FTP to http://hirebuzz.com, after uploaded successfully all dashboard widgets disappear.

We are running WPMU 2.8.4, buddypress 1.0.3 and latest version of plugin.
And plugins are located in mu-plugins

We have the same plugins on a dev site http://hirebuzz.lsdemo.co.za and all is working fine.

Any suggestion please?
Thanks
