hard time configuring. Go to "my classifieds," click on "create new classified,"

I’ve purchased the plugin and I’ve gone through all the configuration as outlined in the setup document. I want a simple classified system where people can post for free, choosing various categories for their posts, and then be able to edit/delete them when they are finished.

I’ve set it up, but now when I go to the my classifieds page to try to create an ad, http://www.okclostpets.com/classifieds/my-classifieds/ I click on the “create new classified” button, and it doesn’t go anywhere. I’m not sure what I’ve done wrong. Can anyone help? Thank you!
