I was working on my blog today and suddenly began having various display issues, seemingly out of nowhere. My home page now displays ALL posts, and the setting for number of blog posts to display on the home page has vanished from my dashboard.The background of the Vigilance theme now displays only at the top of the blog, and disappears at the first post, causing the entire blog to just "float" in space. The credits for The Theme Foundry and WordPress.com now float on top of the entire blog, rather than being static at the bottom where they belong. Finally there is an intrusive smiley emoticon on the widgets bar, which never existed before.
Clicking on a post (i.e. http://jessebull.wordpress.com/2012/05/27/the-wharf-now-on-sale/ ) shows how the blog is supposed to look. Background is in place, smiley is gone, and credits are at the bottom.
These issues just randomly appeared on the home page about thirty minutes ago. What's going on?
Thank you for your help
