I’m trying to upload sample data to [http://slicer.kitware.com/midas3/folder/1118#](http://slicer.kitware.com/midas3/folder/1118#) but it fails:

- log in - successful
- open [http://slicer.kitware.com/midas3/folder/1118#](http://slicer.kitware.com/midas3/folder/1118#)
- click “Upload”
- click browse, select file (17MB)
- click “Start Upload”  
=\> “Error: undefined” message pops up, “Start Upload” button is disabled, the file is not uploaded

Hi Andras,

I granted write access to the SampleData folder for “Data Manager” group. Let me know if you still have issues.

Thanks
