You cannot edit a `registered`. Only higher-level users have this power.

I have use this movie to set up moderators and on 1 of my site's it is no problem and works good. But I do the seem thing on my other site and than I get this:
You cannot edit a `registered`. Only higher-level users have this power.
And the permissions are the seem, so I can not understand why it not works. Who can help me with this?

Since things are working on one site and not on another, there is nothing wrong with the code itself.

You have configured something wrong with your Joomla ACL.

Carefully compare step by step and you should find your issue/mistake.
