The title explains it all. Since updating to 3.3 (I just noticed it) my category urls return 404 errors. Not sure why. I've tried disabling all widgets/plugins and changing themes. No effect.
I read somewhere that deleting the database and re-importing the posts fixes the problem, but I don't know how to do that. So I'm lost.
Need any other information? Any help would be greatly appreciated. Thanks guys.
