When installing a product in Plone you get: AttributeError: navigation_properties

This attribute was removed in Plone 2.1. Most likely you're installing an older product that has not been upgraded to Plone 2.1.

  • Check the README or INSTALL file in the product's distribution for system requirements.
  • Check the products area for a newer release.
  • Ask the product's maintainer or mailing list for advice.
