I'm a real beginner at this so please help me with the simplest (not technical) solution possible. I'm using a theme and put up several posts without making any alterations. My October 14th post has a black background and only shows the first few lines while all of my other posts have a white background and show the entire post on the main page.
How can I edit the October 14th post so that the format is the same as the others?
The blog I need help with is adventuresofyi.wordpress.com.
