[GeneralDiscussion] Site Error/ An error was encountered while publishing this resource.

Sorry to have to post what is probably something very basic but..

All the ZWikis on my Zope site have suddenly stopped working for no obvious reason (well to me at least)

I'm using:

(Zope 2.10.5-final, python 2.4.5, linux2)
Python Version 2.4.5 (#2, Jul 22 2009, 13:43:00) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] 
ZWiki (Installed product ZWiki (ZWiki-0-61-0)) 

All the ZWiki pages are accessible via the ZMI but attempting to display any of them gives the following Traceback.  This traceback is the result of trying to display a ZWiki I have just added.

I'm at a loss to know how to approach this.

Any ideas?

thanks John  ::
