I have just upgraded my wordpress MU from old 1.0 up to 2.8.1 (gradually) and it looks like everything works so far.
However, if I try to add an Editor for a blog this way:
- I create a new user;
- I go to "Blogs" and then click "Edit" and then "Add a New User" and enter the username of the new user and role "Editor"
I get this error message:
Are you sure you want to do this?
Please try again.
That's it. Any ideas how to solve this? I've tried and deactivated (and also removed) all the plugins, but no luck. Also tried and deleted all the cookies.
