A few days ago i have successfully installed plone site an play around with it. This morning i have upgrade the default version of python from 2.2 to 2.3 and selected/deselected some package. Now when i try to access to the plone selecting it and clicking the view tab, the following site error message was displayed: *** Site Error An error was encountered while publishing this resource. AttributeError Sorry, a site error occurred.

Is this a conflict between zope and the 2.3 version of python or i have made some mistake that I'm not aware of? Thanks in advance for any advice ciao, Michele
