Post Issues

At https://roundhousetalk.com/2013/01/dont-ask-dont-tell-still-exists-in-indian-country/ is a good example of what happened. The post now has a blue insert background. I created a new post and same result. Also, whatever caused this also caused my post excerpts created in “Press This” to remove all of my “Read More” link at the end of the excerpt of the home page. I went through the Text tab on the post edit page and there is no different code I can see within my written text. I restored my last backup and no change. So frustrating sometimes. Can someone help me?
