codeigniter 3.1.9 with apache and php 7.2 - routing/redirect issues with sym link

Can't answer that one. If we had that answer, you wouldn't be here; with a problem.

They mean this one:

PHP Code:

$route['default_controller'] = 'welcome'; 


It can't be:

PHP Code:

$route['default_controller'] = 'subfolder/welcome';
