Pligg Support

Hi there, I've just upgraded a Pligg 1 site to the latest Pligg 2.0.2 using the official instructions, but now all the module settings pages are displaying blank (

The rest of the site's pages are displaying fine. There are no errors being recorded in the /log directory and I'm at a bit of a loss. Can anyone point me in the right direction please?

Further info: I've emptied the cache folder (apart from .htaccess) and the blank pages are returning a HTML response header of '200 OK'. The site is sitting in a subdomain.
