Greetings!

I had sixteen images with sixteen different captions in the Featured Content Slider on this page: http://sfiaf-festival.nationbuilder.com/home  They were working up until a short time ago, but now they are all gone. They are not listed under the Settings for /home.  It's as if they were deleted.  But nobody except me has access (or the knowhow) to do that and I didn't do it. 

Has this happened to anyone else?
