Advanced search not possible if you already use a custom form for ad submissions
I came across this tutorial to add advanced search to Classipress (an essential feature for any classifieds/directory): http://docs.appthemes.com/classipres...vanced-search/
However it seems if you already have a custom form for adding listings, you can't create another one for advanced search since you can't select categories again. This must be a bug, surely??
