Blank screen when not logged in to wordpress

Hi there, I am having a problem with a site I am creating using the pagelines DMS2 theme, the problem relates to the Directory plug in. If I am logged in to wordpress, I can see the directory listings I’ve created fine. If I am not logged in to wordpress the page is completely blank, nothing displays on screen. Problem can be seen at and then click on the Directory menu item in the top right of the screen. I really want the directory to be visible even when the user is not logged in to wordpress.

Any help you can give would be great, as I’m a bit stumped. Thanks
