Hi!
Actually this is better, because it’s update proof. Local changes can get overwritten easily with an update process. Moreover the plugin JS is compressed and built after testing. Unfortunately this solution was only tested in few browsers, it might be impossible to clear the placeholder on some versions.
I’m not able to see the website, I’m getting this red screen: http://i.imgur.com/yT7AYio.png
Can you please check it?
