Well here is the code block in bulkupload which is stopping you related to noupload diewell
Code:
Content visible to verified customers only.
Therefore to me looking at that code which of these is off a little. Is global upload switch in admin options set to yes? Is under usergroup permissions are unregistered users set to upload?
Basically one of these two is blocking your upload. Now try removing these this in bold and see if it works
Code:
Content visible to verified customers only.
