UPDATE: (VERSION 3.3)
The bug is now fixed. This plugin is just awesome. highly recommended. 5 stars!
I was very happy at first with this plugin as it proved to be very useful. After installing this plugin and other plugin I realized that my "Add Media" button has stopped working in the post/page editing area. I googled the problem just to find a plenty of possible causes. I then decided to check if one of my recently activated plugins might be the cause of the error, so I have de-activated all my plugins and started to activate them one by one and check for the existence of the problem, just to come out with the sad conclusion that this plugin -alone- is the source of the problem.
I wish if the plugin's author could check his code and fix the problem as I was really happy with it. I gave it temporarily 3 stars to give it a chance to get fixed, and then it surly deserve 5 stars, or otherwise, I think it should take only 1 star.
