I have installed this package and followed the instruction, but get the following error message:-

 The PKB Site Setup is not configured correctly. Please verify that the category group name is correct and that the group is active.

If I change line 345 of the Knowledge Controller to  siteName = 'Knowledge' (Knowledge is my site name) then I get past his error and get a partial resutl the layout is not very good, the search does not work, and if I add ?lang=de to the URL I still get English descriptions etc.

I think this means that my settings are correct, but that the controller is not picking up my site name automaticaly as this line is only triggered if the site name is null.

Has anyone any ideas how to resolve this issue?

Thanks
