Custom Post Child 404 Permalink Flush Not Working

Hi guys — I’m in a pickle and unfortunately, have almost zero working understanding of mod_rewrite/apache stuff. Here’s what’s going on:

I’ve got a hierarchal custom post type with parents and children. On my test server, before I can see any of the custom posts, i needed to go to the permalinks settings page and hit refresh. Then I can see parents. When I hit it again, I can see children, and I’m golden.

On the actual server (my friend’s shared hosting account) — I follow the same process and the parent’s come through — but not the children. I know it’s not a plugin issue, because it’s true with them all turned off, and also on the test server with them all turned on.

The child posts DO come through when i have the settings at default permalinks — so I know the posts are actually getting created. I’m thinking it has to be something on the shared server — any ideas what to look for? It’s so weird that parent’s work but children don’t…

Thanks!
