Problem with Manage Layouts page

Hi,

I'm trying to get TB running on a local install to play around with it following the webinar. I've followed the install instructions and have installed both dependencies and disabled the compatability macros but whenever I click on "Manage Layouts" I get a page with the default layout and the correct title but no content - i.e the div with class "pagebody" is empty.

I don't have any errors appearing in FireBug but in the server/application log files there is one error:

2009-05-09 14:18:09,882 INFO [http-8090-5] [admin.actions.plugins.ManagePluginsAction] execute Plugin operation: null attempted by id:98305

I suspect its a configuration error on my part rather than a bug but do you have any suggestions?

Thanks, James
