“Resolved”. Sounds good doesn’t it? Doesn’t it just sound like my time and effort paid off nicely?
I wish I could say that. After trying a few ideas, I had to set the whole problem aside for a week or so. In that time the latest WordPress was released. So, as I do, I backed up my blog and upgraded. This had the lovely side effect of fixing the Category problem.
So I still have no idea what fixed it, but it’s fixed. So, yay.
