When I first installed WordPress this option worked just fine. This past week I have had nothing but problems with getting any option under Insert/Upload sections to work. This includes inserting an image, Inserting a video, Inserting Media, etc. This is not working for both pages and posts. I am not sure what happened. I did not mess with the PHP code or anything. Here is a screenshot of what I am talking about it is the options just to the right of the Insert/Upload section of a page and post.
