I am using a child theme of wp twentytwelve and my blog page is set to show the full post content rather than an excerpt.
You don't have a setting to 'show add this on content' only to 'show add this on excerpt' so I assume this is why it's not showing up.
It does show up on 'categories' and 'archives'
Is there any way I can set the plugin (i.e. add code) to show on the post content?
