[Zope] AttributeError: @@plone

24 Nov 2010

      Dear Zope Users,

we are trying to get an old plone application to work and keep getting 
the error message "AttributeError: @@plone". Some posts suggested it 
might be a zope/plone conflict, that's why we are also posting this to 
the zope list.

The versions we are using are:
Python: old=2.4.4 <-> new=2.4.6
Zope: old=2.9.6 <-> new=2.9.6
Plone: old=2.5.3 <-> new=2.5.3

We have already tried the migration assistant, but no luck. We moved the 
application by simply copying the instance directory and also tried 
setting up a new instance with plone 2.5.3 and installing the products 
manually. Both yield the same error.

Is there anything special to consider when copying an instance from one 
server to another? The user permissions are set to the zope user.

The complete traceback is as follows:
