Having problems with permalinks, the "listings" and category listings don't work

Hello, I cant seem to get links to the Directory plugin to work, I have had success with using the shotcode as you can see in Directory:

http://ceric.org/directory/

But the "listings" page or links to any category do not seem to work:

For example the links from this page:
http://ceric.org/directory/

Like: http://ceric.org/listings-category/events/

Takes you to the homepage.
