Strange category issue here, and can't seem to find an answer anywhere. Apologies if this exists elsewhere.
Here's what's happening.
1. I have several categories created several WP versions ago what work just dandy.
2. If I try to rename the title (not touching the slug) of one of my existing categories, it will stop displaying posts when I view it on the website.
I can still see the new category name associated with posts in the Posts admin screen...it just doesn't show any of those assigned posts when I click it on the website, as if there were no assigned posts.
The very odd thing is that there is still a link to comments for the category, and if you hover over it...it's the comment link for the first post that SHOULD be showing up under the category...but nothing else is on the page.
3. Same thing happens with new categories. Create new category, assign posts to it, view cat on website...no posts display (except for comment link to the top post that SHOULD display)
I'm at a loss on this one, and about to start diving into the php code. Any insight would be amazing, even just a point in the right direction.
