WYSIWYG editor, Upload media button not working on WordPress 3.9.1

I’m currently running the latest version of WordPress. However when I try to add a photo via the Add Media button on the page/post editor and I click on it, nothing happens. The “Text” Tab is unresponsive and so are many other buttons throughout the Edit page admin area. I opened up the console and saw an error that might be the cause of the problem, it reads:

Failed to load resource: the server responded with a status of 403 (Forbidden):http://backinmotionpt.com/wp-admin/load-scripts.php?c=0&load%5B%5D=hoverInt%E2%80%A6,editor,media-upload,w&load%5B%5D=ord-count,wplink,wp-fullscreen&ver=3.9.1

It seems like its not loading the script that might be in charge of handling the UI events.
Am I correct? How do I go about fixing this issue?
