Ubercart

I am trying to use the uc_wishlist module version 0.7 on a Drupal 5.22 and Ubercart 5.x-1.9 website. I am not eager to perform a full website upgrade to Drupal 6.x and Ubercart 2.x and would prefer a fix if possible.

The module appears to work fine for a logged-in user. But, anonymous users to the website see the following error message appear in a red box on the home page.

Any ideas, fixes, etc.?
