 * Hello!
 * I have several forms on my site, and since I updated to the latest version of
   WP (3.8) and the latest version of Ninja forms (2.3.8) i get an error. On each
   line it says “Notice: Undefined variable: address_class in /storage/content/28/
   187028/woodeye.se/public_html/wp-content/plugins/ninja-forms/includes/display/
   fields/display-fields.php on line 362”. Isn’t the latest versions compatible 
   with each other?
 * Oh, and I also do use a checkbox, and the bullets is visible all of a sudden.
   And the boxes align vertical rather than horisontal like they used to before 
   the update.
 * The website, with the form ([http://woodeye.se.preview.binero.se/en/woodeye-5/](http://woodeye.se.preview.binero.se/en/woodeye-5/))

 * Hi johanstroom,
 * This was recently [fixed on Github](https://github.com/wpninjas/ninja-forms/pull/136).
   Make sure you update to the latest version when it’s released. 🙂
