'isPrincipiaFolderish' of None, acquired through (Products)

by Mikko Ohtamaa — last modified Dec 30, 2008 03:08 PM
Skin rendering fails and hiddenStructure becomes visible. Plone default styles are missing, because Plone default CSS seems to be not used. If one runs in debug mode, an exception traceback is available in event.log.

Solution

You touched something you shouldn't have in base_properties.prop, the file giving Plone CSS color definitions. Restore orignal values.
