I just upgraded and now I see a post in the default category, but there's nothing there. I've never used it.
I click on the number link and it tells me that I'm looking for something that's not here.
I did install the Ultimate Category Excluder plugin, but it's showing through the sidebar still. Since it's not empty, it's showing, but there's nothing in the posts in that category. I've checked a few times.
Any help would be great, thank you in advance!
