'ClassTypeBehaviourProxy' in Knowledge build or when working in Console

Version 2
    Question

    We are getting an error in our Knowledge build and while we are working in Conosole.  The error is:

     

    Unable to find reloaded metadata object 'ClassTypeBehaviourProxy' with unique identifier <GUID>

    .  Please restart application.

    Answer

    This is caused by the XML design cache being out of date.  To fix the issue just delete all the folders and XML files located at:

     

    C:\Documents and Settings\Default User\Local Settings\Application Data\Touchpaper

     

    On the server.  This can be done in a live environment without a scheduled system down.  To prevent the problem recurring try to avoid making design changes whilst having caching switched on.
