How to resolve my Open Atrium installation error? I am very new to open atrium.  I installed Open Atrium and now the home page is not loading properly. Instead I have the following error:


  Warning: file_put_contents(temporary://fil29F1.tmp): failed to open
  stream: "DrupalTemporaryStreamWrapper::stream_open" call failed in
  file_unmanaged_save_data() (line 1936 of
  C:\wamp\www\openatrium\includes\file.inc). The file could not be
  created.
Try this

open -> admin/config/media/file-system

Change Temporary directory -> sites/default/files
