I had a tag that was associated with quite a number of posts and decided to convert it to a category via the Dashboard>Manage>Import>Categories and Tags Converter.
After converting it to a Category, the former tag appears correctly on my Archives Page ("what you saw") as a Category, but is still appearing on the individual Posts as a tag and not a Category. I logged out and did the cookie dance (not the hokey-pokey) and emptied my browser cache, but the new category still shows up on Posts as a tag.
Not really a problem, I guess, but am just trying to get my head wrapped around the reason why it wouldn't show as a Category on Posts.
Any thoughts?
