I have seen the same problem; the getSize method isn't accessible to
RecentChanges, even though the Authenticated User has the View permission.
Only when you explicitly give Anonymous the View permission on the Folder
(or every individual ZWiki page), will RecentChanges render.
This is caused by specific 'safetybelting', implemented by Jim Fulton, to
mitigate the risks of ZWikis becoming an easy entry point for a Trojan
With the new security policy in Zope 2.2, this is no longer necessary, and
you can comment out the restriction. Just remove or comment out the
'validate' method in the file Products/ZWiki/ZWikiPage.py and restart your
Zope server. Note that on a pre-2.2 server, this means that any DTML code
executed in a ZWiki page will be executed with the rights of the viewer!
If you still have problems, make sure that the Owner of the RecentChanges
object has rights to 'View' the ZWiki pages.
The Interfaces Wiki (and all other Zope.org Wikis) allow Anonymous to
View, only Editing and Adding new Wiki pages is restricted.
