I installed the new version of the Blessings theme yesterday 5/1/14 on the WP v3.9. The shortcode and the layout constructor still does not work. I’ve added it to my ticket. I added TablePress plugin and that activated some type of shortcode but that also does not work and is not exactly the same shortcode that is showing in your documentation.
You would need to update the theme in order to get the shortcodes working properly. You can update the theme through the WP admin panel or via http://FTP. In the Blessing WP theme the shortcodes are in theme files and not being separated to a plugin. Please make sure to clean your browser cache. If you would need our help with theme update please submit a ticket and we will help you regarding this matter.
