    I have searched high and low for the answer to this - still no joy.

    I want to display all categies from all blogs in my multisite wordpress install to 1 page. Even if there are no posts under that category. I have tried WordPress MU Sitewide Tags Pages but not right.

    Any help please.

    Have you tried to use the switch_to_blog function?
    Here's an example how to show all posts:

    Try to use get_categories instead of get_posts.

    In such cases I'm always curios to know why anybody would like cross listing all the categories. I'll be happy to know the reason, if you don't mind ;-)

    Well, sitewide tags is what I would recommend. Why isn't it "not right" for you?
