The sidebar on my blog has just disappeared and in it's place is a smiley face (which makes me think someone may have hacked into my site). I added one plugin today (Better Internal Link Search) but deactivated it in case that was the issue. It was not. I have been using Theme 2010 for two years now and had no issues. What could be causing this? When I go to Appearance/Widgets, I don't see the sidebar there at all. Help please!
