In Konqueror no other buttons beside the "Choose file" button and the "Submit" and "Cancel" button appears. After choosing the file I get the error message: "Please upload a file".
In Firefox an "Upload file" button is present. After choosing the file I pressed this button and obtained the following cryptic message: "Error Code: HTTP Error, File name:tbb_misc.dif, Message: 400"
Thanks in advance,
