Directory: published listing doesn't load but preview OK


I've been pulling my hair out for the past day, and can't figure out why I can see my listing while it is "pending" approval. However, after I "publish" the listing, I get a redirected 404.

Any ideas on how to fix this? I had things working before, but then I changed my directory structure and some settings in CustomPress. Now, I wish I had not done that...
