Unable to add content to new Plone site: ValueError: Unable to find update_version_before_edit exception

Just finished a successful install of Plone 4.2.1 on CentOs using the unified installer. Once logged in I cannot add any content.

I get the following error:

Traceback (innermost last):

I've already run bin/buildout -n to update components. Thanks in advance for any help.
