[wp-testers] Subcategories

[Garrett Fitzgerald]

Most of my subcategories have gone missing. I checked the DB, and they
seem to be intact. I selected one of the missing ones, and changed the
edit URL for a top-level one to point to the missing one. It brought
it up properly, and I changed it to not have a parent, saved it, and
saw it appear in the category list.

I clicked on it, and set it back to the original parent category, and
it disappeared again.

I haven't yet tried the current build, because for some reason, I
can't connect right now.
