Hi 

I am getting exception while opening File i uploaded in "Page Files" i.e.

Stack Trace:

[NullReferenceException: Object reference not set to an instance of an object.]

   EPiServer.Web.Hosting.Versioning.VersioningFileHandler.GetFullPath() +27

   EPiServer.Web.StaticFileHandler.ProcessVirtualFileEx(VirtualFileEx virtualFileEx, HttpContext context) +194

   EPiServer.Web.StaticFileHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state) +132

   System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +391

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +262

On few files this error is coming,What is the cause of this error and how i can fix that.I don't want to upload files again. 

Thanks in Advance!
