Hi, I noticed that there's a bug in the getOldVersion() method in page.py. The error is in line 309, when it calls site.loadrevisions() the third parameter is 'revids=oldid'. loadrevisions() attempts to iterate over that, and fails. The doc for getOldVersion() says 'oldid' should be "the revid of the revision desired", so I patched line 309 to use 'revids=[oldid]', and that seems to work just fine. Cheers, Morten
