    Hello Fujiy,

    Have you made any manual changes to the database? The error is thrown when we try to remove the object from the database but we could not find the StagedPage id there.

    So we query two tables

    [StagedControlLink] and [sf_StagedPageContent], so in one of the the ID of the page that you are trying to delete does not exists.
