make sure that humanize used is the latest version

update the function to access to correct variable

e.g. 'Humanize' vs 'humanize'

[rpbaltazar]

 if(typeof humanize == 'undefined' || typeof humanize.filesize != 'function'){
    // Replace the url with the latest compatible version
    $.getScript("https://cdnjs.cloudflare.com/ajax/libs/humanize-plus/1.5.0/humanize.min.js")
  }

  var getFileSize = function(filesize) {
    return humanize.filesize(filesize);
  };
