So my public page navigation menu (http://exhibits.gelman.gwu.edu/omeka-dev/) is coded via header.php:
' <?php echo public_nav_main(array('Browse Items' => uri('items'), 'Browse Collections'=>uri('collections'))); ?>'
...and it includes two sections, <b>About</b> and <b>Test</b>, that I never included. Even though the folders to which these two choices link aren't even in my FTP directory, they still call up pages.
How I remove these from the array, and place them elsewhere>
