I too had this problem - took me ages to find this post and when I did I followed the advice to check the file type being passed.
Turns out it looked like this: 'aplication/unknown' - why I have no idea but explains why the uploader was spitting the dummy.
Anyway, because it's 4:30pm Friday and because I'm dying for an ice-cold Steinlager I fixed the issue by amending this line:
Code:
'pdf' => array('application/pdf', 'application/x-download'),
to:
Code:
'pdf' => array('application/pdf', 'application/x-download', 'application/unknown'),
In the file located here: system/application/config/mimes.php
I realise this is bad programming practices but like I said, it will band-aid that irritating error message until I can figure out why my PDF's are so crappy.
Cheers,
Muppit
