Thanks for that, the error it is producing is as follows:

"Catchable fatal error: Argument 2 passed to CategoryViewer::__construct must implement interface IContextSource, null given, called in /home/sites/staffs-ecology.org.uk/public_html/partners/extensions/CategoryTree/CategoryPageSubclass.php on line 9 and defined in /home/sites/staffs-ecology.org.uk/public_html/partners/includes/CategoryViewer.php on line 61 "
