Default Administrator vs. Admin Role
There is a difference.
As a user with an Admin role I can't change settings for some of my plugins. For example the Spoof plugin and the FileUpload plugin settings can only be changed by the original Administrator. A user with an Admin role gets a permission problem.
Why is this? And can I fix it?
