Problem with new Directory + CustomPress

Trying to set up a brand new installation of Directory + CustomPress.

Everything seems to basically be fine, but the Website field I added to the listings is giving me an error on the Add Listing page:

You will see the error at the bottom:

Fatal error: Call to a member function display_custom_fields() on a non-object in /home/content/60/9680660/html/wp-content/plugins/directory/ui-front/general/page-update-listing.php on line 166

This is where the Website field should appear. It’s just a simple text box with a website regex.
