Up to Table of ContentsThis FAQ applies to: Any version.
This can happen if you run Plone with the wrong version of CMF. Plone 1.x needs CMF 1.3.x, and Plone 2.0.x needs CMF 1.4.x.
The correct version of CMF comes bundled with Plone releases, so unless you have changed this manually, you should have the correct version.
Check the release notes for your version to see the exact version recommendation.
