If I set the "access zina" permission to unchecked for the anonymous user and then visit http://my.server.com/music without being logged in to Drupal, I get a PHP error in the footer of the page:

  Fatal error: Call to undefined function ztheme() in /home/jsquyres/public_html/sites/all/modules/zina/zina.module on line 300

Here's the support info from my "Help and Support Information" page, but per http://drupal.org/node/844292, I think it might be incorrect about the failed test for the Zina files directory:
