var file = document.getElementById('fileToUpload');
fileName = file.files.item(0).name;
fileSize = file.files.item(0).size;
var fm = document.getElementById("form");

console.log('action = ' + action);
document.getElementById('form').action = action;
document.getElementById('fileSize').value = fileSize;
fm.submit();

Which security software (firewall, anti-virus) do you have?
Did you make sure that your firewall or anti-virus software isn't blocking such uploaded content?
