updated from 2.2 version to 3.5 and my entire blog is out the window... WHY?
Because in the 3.5 version, the "Post" page gets automatically assigned to a category and if you don't create a "Dupe" of your Post-page under "Pages" then WP would throw you a "Not Found"
Weird and strange and - incomprehensible why WP 3.5 is now going down this backward-path.
It's like having a car in your garage, but unless you buy another car, exactly the same and place it into your neighbors garage, you wouldn't be able to drive out your own car. Uhm... yeah, huh... mhh, makes complete NON-sense.
PS:- What's the story about the "check-box" next to the category? Why having it if you can't "UN"check it? Should this be considered another extra free WP fun?
I tend to start believing, the latest WP version has too much fun built in, it's no longer fun! ;-)
