I just wanted to say I noticed the same thing has happened to my site! I just noticed it this evening. My footer has disappeared but every time I edit my site it reappears, it is so odd. It will not correctly save the page with my footer and I've tried every web browser. The colors on my header have changes as well and but reverts back to my old colors when I edit the site. My social links disappeared on my header as well. Hoping we get an answer to this!
