I'm not sure what changed or why things look like that, but the fix is pretty easy. Basically, there is a style in your template which says that all backgrounds are transparent, and that's making something from the Facebook widgets go a little crazy.
If you add the following to your template's CSS file, it looks like it should fix you right up:
.sourcecoast.facebook {
background: white;
}I hope that helps, but if not, let me know.
Thanks,
Alex
