I installed cakedc users 9 in my site and when I access it it gives me an exception of “The “Authentication” alias has already been loaded. The `load` was not defined in the previous configuration data.”  
Before that I installed the authentication and authorization plugins and was using them, what do I have to change so that it works with cakedc users?
