I have a Plone2 web site since few months and I get a very strange error since this morning : Zope returns this error "You are not allowed to access 'listFolderContents' in this context" when I try (for example) to display folder content from the Plone interface. What is strange is that the "insufisant_priviledge" page is not displayed but the browser waits until it times out. I am manager and my provider sais he changed nothing on the server. I investigated and found it is the product "CMFMessage" that generates such error but ONLY on my welcome page. The error log sais this : Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ __traceback_info__: [o for o in msgFolder.listFolderContents() if not getattr(o,'acknowledged',0) ] Module Python expression "[o for o in msgFolder.listFolderContents() if not getattr(o,'acknowledged',0) ]", line 1, in <expression> I really don't understand : any ideas ?
