I recently installed the participants database on a fresh install of 3.4.2. Most of the plugin seems to be normal, however, when I click on the Manage Fields setting, it only shows a mostly blank page with the page title and no fields to manage or customize. This is proven out when I add the [pb_signup] shortcode to a page and it only displays the SIGNUP button and that is all.
I am operating on Ubuntu 11.04. Any help would be appreciated.
