Blank space after latest post

My page was running perfectly until I posted my latest post this morning. This post marks my 10th post on the blog/homepage. All of a sudden there is a huge blank space between the end of the post content and the end of the actual post (where the sharing/comments section is). I have checked this in Safari and in Google Chrome. I’m not sure how this happened or how to fix it. I posted another post after that one (an 11th post) and it did the same thing, moved down all posts and created a blank space in the latest post. I found this post however the topic is now closed and the author never describes how he fixed the issue. I’m not very knowledgable in css or html. How can this be fixed?
