get_instance error - Class 'CI_Controller' not found - AlissonSaN - 09-28-2017 In my "helper" function in the "application" folder, PHP Code: if ( ! function_exists('_return_config_xxx')) I call : $ CI = & get_instance (); return $ CI-> config-> item ('XXX'); and I get the following error: Code: Fatal error: Class 'CI_Controller' not found in /home/www/aprendermais.render.com.br/html/system/core/CodeIgniter.php on line 369 RE: get_instance error - Class 'CI_Controller' not found - InsiteFX - 09-28-2017 We need more information, like your directory structure where are you calling that function / method from? If you have moved the application and system folders then you have to edit the index.php file and tell it where they are located. RE: get_instance error - Class 'CI_Controller' not found - g4nar - 10-04-2017 your helper in in application/helpers/ ? RE: get_instance error - Class 'CI_Controller' not found - Narf - 10-05-2017 You're calling this helper prior to controller instantiation (likely in a pre_system hook, or a core library extension), and you can't use get_instance() in that case because what get_instance() does is to return the controller object.

I agree with the above comment. If you provide the logs, we can have a look.
