Just upgraded to WP 3.3.1, and I am having problems with post categories. They are unchecked when I am editing a post.
I tried deactivating all my plugins, and to activate the standard twenty eleven theme. The problem still exists.
The server is running php version: 5.2.14
MySQL v: 5.0.41
And runs on a Linux machine.
Anyone else thats having the same problem?
I tried upgrading my personal blog. Its not having the same problem, its located on a different server though...
