Hi,

I am having a heck of a time with controllers with plugins. I am  
using the “acts\_as\_authenticated” and after a second request I get  
the following error from one of my controllers inside the plugin:

“A copy of AuthenticatedSystem has been removed from the module tree  
but is still active!”

I searched the mailing lists and I was told to put “unloadable” in my  
controller. Which I did, but now I get:

“uninitialized constant AdminController”

This is driving me crazy, any ideas why I am getting an uninitialzed  
constant?
