I don’t know whether or not this will work, but you can try going to your preferences and disabling the category module.

If that doesn’t work, I don’t think it’s possible to disable it; it’s a Wiki Feature, which only administrators can disable (see Help:Category § Category Exhibition for more informa tion about this Wiki Feature).

You might be able to disable it in your Common.js or Global.js, but I’m unsure about that.
