Editing and "Ended Ad" from the Ended Ads page doesn't work

I am not sure if this is a bug or what. Here is a description of what is happening using the Classifieds plugin. I go to an ad and click the end ad button. The ad ends like it should. Then I go to the "Ended Ads" page and there is my ad that ended. All is working fine so far. The problem is when I try to edit the ad from the "Ended Ads" page. WHen I click edit add to edit an ad (from the Ended Ads page) it takes me to a blank page instead of the edit ad form.

How do I fix this?

If I edit and ad from the Active Ads page it works fine.

Thanks for your help!
