I don’t think you have configured the JM Twitter Cards plugin correctly, as I don’t see any of the markup required in any of your pages. You could try using the official Twitter-provided Wordpress plugin instead, if you like.

If you post a link in a Tweet, the Card will show up (in the iOS and Android mobile apps, in the timeline; on the web, there will be a View Summary link you can click to open the Card)
