Quote:I can access this config value from the first controller’s view. But when I go to other controller (that not extend from MY_Controller class) clicking a link in the first controller’s view, I can’t acces this config value from this second controller’s view.
The config item isn't actually 'written' to file. It is just set for that request. Hence on a new request where you don't explicitly set the config item (any controller not extending MY_Controller), the config item won't exist.
