There are some formatting peculiarities here. I can see the original text here:
(html comment removed: wp:heading )
<h2 id="what-i-ve-been-up-too">What I've been up too</h2>
(html comment removed: /wp:heading ))
But what I see in the post is this:
(html comment removed: wp:heading )
What I've been up too
(html comment removed: /wp:heading )
You might want to try Markdown code instead of HTML. For example,
Heading
## Heading
Additionally, images can be embedded directly in the editor, or with the following code format
![image caption or title](image URL)
I hope these hints help!
