[Zope3-Users] zpt pages though ZMI

Sat Sep 23 18:00:42 EDT 2006

Hi,

Your problem is
in /home/hassan/HOMEPAGE2/modules/ISI/skin/template_tablelayout.pt and
UnauthenticatedPrincipal does not have attribute 'title'.

Check Boston skin template which first tests for authenticated user
before calling request/principal/title.

Regards,
Darryl
