Hi, and I already know what is going on. This is all because the label on fileUplad button depends on web browser interface language and not on preferred language for dispalying pages. So if you set locale on English but the interface of the browser is Polish the label of the fileUpload button would also be in Polish. And this is not a good message :( Thanks for the link concerning styling the control.
