Argument Error (A copy of SectionsController has been removed from the module tree but is still active!)

U have seen this error frequently in rails 2.3.3.. So what u have do is just call your controller(which is shown in the ArgumentError) explicitly in your dependent controllers.

Add this line on top inside the class:

require "_controller"

This will not throw the following error...
