I can't seem to get the plugin to work. I changed the default location for the files and I got a message that permissions for the folder are not set properly. So I changed them to suggested level and even beyond. At that point when I try to upload file I don't get any messages but the file is not attached and the form resets itself.
I also tried default location and I get the same result - no error message, file is not attached and the part of comment form where you upload te flie resets itself.
Even more interesting, is the fact that when I check the destination folder on my server, the file is there.
