Steps to reproduce:

  - Enable staging

  - Add the D&M portlet to any page

  - Add a repository (tested with Alfresco + CMIS AtomPub)

  - Publish the changes

  - Go to the staged site > Publishing > Staging and disable staging

Expected: Staging is disabled

Actual: A generic error message is displayed, and staging is not disabled.
