I have just been out to a client of mine that uses Zope 2.3.3 on Windows 2000. They found that all of a sudden nobody was able to view part of their site. I did some checking and found that they were getting permissions errors on all sorts of obscure things. In one case they got permission denied on a particular value returned from a db query. The permissions on the query were ok, and they could run the query, but could access one of the values returned. No matter what user/roles were used. In another case they were denied access to the 'title' property of a DTML document, but access to all the rest of the document was ok. After about 2 hours of frustration. I exported this section of the site out to .xml then imported it back again. This fixed everything and all is ok now. I have no explanation of what happened, if anybody does that would be nice. Also, if someone experiences the same thing, export/import is a potential fix. Tom
