As I scroll down through recent posts, a black bar stating that I am using Coraline appears at the bottom of the page and blocks further scrolling, as well as covering the "previous posts" arrow and link. This began about 10 days ago. I am surprised and a bit alarmed to see we no longer have any real support assistance, I am not a particularly sophisticated blogger and don't want to experiment and make things worse. Thanks for any "Help For Dummies" on this.
The blog I need help with is artandhistory.wordpress.com.
