I am running 2.8.4 and have had no problems with Category Order until now. I moved a cat out of its parent to be its own and now no matter where i move it in the order it won't move.
kperrone.com - check out the site and see what I mean. the cat "Nerd Stuff" is the one I'm trying to move but it won't budge. Any other cat will move as I wish but this one.
Any ideas? I've tried disabling the plugin, deleting, and reinstalling.
