Pull out Category-less Ads
I have several ads that have now become category-less. I want to pull up the list of these category-less ads on the wordpress admin backend.. does anyone know how I can modify the URL below (showing Ads for bicycles category) to show these Category-less ads? I tried removing the word "bicycles", even tried using space but it doesnt pull the list.. any thoughts?
