I used:
Post Sorting Reloaded plugin to alphabetically order posts in categorie pages, I'm also using link category post to get lists of all my categories alphabetically on a "view all post" page.
but the navigation on 1 post on page pages is still not alphabetically.
I've got the most recent atahualpa and wp and i didn't change the page template (as far as i can remember). Here's an url that shows what im talking about
:
http://www.bushcraftvereniging.nl/wiki/pemmican/
You see the post "Pemmican"
The next is trapper and the previous is bannocks.. but there should be a lot between the b and p.
(note that this page was only created 3/4 days go and is still very empty)
