Listings Not Showing From Category Links

I'm having an issue with Directory. I've created categories and listings with no problem. The category links show properly on my page but when I click on a category to view the listings, I get a blank page with a header "Archives for: ‘<insert category name>’".

If I preview individual listings from the back end, they do appear so I suspect there's something happening between my archives page and Directory.

Any help in sorting this out is appreciated.

Cheers,
Khris

Troubleshooting:

* WP 3.4
* Latest version of Directory
* No buddypress installed
* I've reset permalinks (is there a preferred permalink setting?)
