Problems after running EWWW Image Optimizer

I ran the bulk image optimizer, and when I went back to the site after it finished, the site has lost all of its formatting. You know when you login to a website that doesn’t load properly, and all the text is the same, no images load, and formatting gets all screwy … thats what is happening

Figured I’d try and post before diving into what could have happened…

Thanks for any help!
