was driving me INSANE. Wouldn’t work. There was no button appearing for me to browse for images and upload media. But PresidiaCreative.com came up with the WordPress fix:

  1. Download the WordPress zip file from WordPress: http://wordpress.org/latest.zip
  2. Next, extract that zip file to your desktop.
  3. Now, open your FTP client and connect to your server that is hosting WordPress.
  4. Navigate to /wp-includes/js/
  5. Re-upload /swfupload/ from your desktop (in the same directory) and replace the files currently on your server.
  6. Clear your browser cache.

Bless ’em 🙂
