This past weekend (October 20-21) when I logged into the backside of my blog, I noticed a slight change in appearance overall and a major change in the way my widgets page appeared. This was not caused by any change or update I made to my blog.
When my Monday blog post went live on October 22, the widgets that used to appear in the right-hand side of my post page weren't there. Instead they're appearing underneath the comments, on a blue background. You can see this here.
You can see what it should look like on this page here.
If anyone could tell me what has caused this and how to fix it, I'd appreciate it.
