Site formatting stripped

Yesterday, https://www.louisvillederbyhomerental.com appeared fine. When I looked at this morning, however, the images were all gone and most of the formatting was stripped too. I hadn’t made any changes to the site in the meantime. Also I use this same theme (WooTheme’s Canvas 5.6.4) and version of WordPress on zacheverson.com and it works fine there.

Any idea what’s causing this problem and, more importantly, how I can fix it? Thanks!
