I've been trtying to create a dfwiki in our moodle installation (v 1.6.1) and if I set it up I just get the error message:
Course module is incorrect
And that's it - pressing continue takes me back to front page.
Thing is dfwiki has some features that would be really nice to use - is there a version out there that works or a fix for this bug (can't upgrade moodle till July as there's courses runnign and last upgrade from 1.5 to 1.6 saw us lose all the course content with change to UTF-8 so you'll understand my nervousness!)
