NOTE: the file CAN be successfully uploaded in case the Description/Subject is filled in for the doc (the Title field should already be pre-filled), e.g. you should fill the Description/Subject field for Document Properties for doc, pdf,.. files (open your doc via Microsoft Word, click File -> Document Properties)
