It appears that even basic HTML code is being stripped from the visual/HTML editors:
1. create post
2. drop in two paragraphs of text
3. switch to HTML view and add <br /><br />
between the paragraphs
4. switch to visual (looks good!)
5. switch to HTML and code is gone.
Even if you drop in simple <p>
tags it gets removed when switching between editors as well as when you publish.
If you drop in a post into the visual editor, shouldn't you be able to see full code when you switch to HTML editor including paragraph tags?
Any thoughts as to how to get simple html code to work?
