Looks like you might have copy/pasted the code from my previous reply. You can do this, but you must paste into the WP post editor while on the “Text” tab. If you are in the “Visual” tab, you have to manually type the shortcode in or it will not work. This is not a Connections bug but the way the WP Visual editor works. When you paste in the Visual editor, the HTML from the site the code/text was copied from will also be pasted. It is this that can can break shortcodes / keep them from working.
Hope that helps!
