I'm trying out the Q and A - FAQ Plugin, and I have a FAQ page that's a parent Page, set with the [qa] code. However, the FAQ page has child pages. I've set QA categories so I can use [qa cat="some-cat-slug"] on those, to break them up into sections.
Unfortunately, the plugin renders any child pages of a Parent that has [qa] in it to go to 404's. Even though the child Pages exist, if the FAQ is on the parent page, the children all go away.
I also attempted to remove the [qa] from the parent page (it was *named* FAQ - so I don't know if the name itself has something to do with it) and just leave them separated on the child pages, but the children were still 404'd. I don't know if this holds, though - because once I deactivated the plugin, the child Pages still went to 404. When I reloaded, the child pages went to the home page. When I tried a third time, they finally did what they were supposed to do - so it seems like the system was playing "catch up" with the plugin being shut off.
In any case, after disabling the plugin, the child Pages worked fine.
A NOTE: the plugin - aside from the above - works perfectly fine. It's actually quite nice. I'm giving it 4 stars - it would be 5 if the child Page thing weren't an issue, because it is a really good one :)
