Error when copy a page structure
If you experience that you get an error when trying to copy or export/import a page tree the reason could be that you are missing some files in the VPP (7.0) or Appdata(7.5).
What you then need is to find what files you are missing. I have made a small utility that loops thru all properties, checks the IReferenceMap, and finds all documents and check if the file actually exists on the disk.
It can be added as a gagdet: 
An will be shown like: 
The code is simple and is
[IFrameComponent(
Url = "~/Custom/Plugins/CheckFiles.aspx",
ReloadOnContextChange = true,
PlugInAreas = "/episerver/cms/assets",
Title = "Check files used",
Categories = "cms", MinHeight = 100, MaxHeight = 500)]
//Update: In EPiServer 7.5, the base class to use is: EPiServer.Shell.WebForms.ContentWebFormsBase
public partial class CheckFiles : ContentBaseWebForm
