Why am I no longer seeing click-through stats when using the WordPress plugin?

We’re using the Swiftype’s WordPress plugin, and last week we switched themes. Now my click-through stats stopped working.

Please help!

The Swiftype WP plugin utilizes Wordpress’ post_class function in order to add the necessary classes to each post and track click throughs. Make sure your theme is using this function so Swiftype’s JavaScript can track a successful search conversion.
