Can someone check base_url() and base_url("param")

You do not need the base_url in route_to if you have defined a route for that controller.

Example:

PHP Code:

$routes->group('', ['namespace' => 'Insitefx\Admin\Controllers'], function($routes)
{
    $routes->get('dashboard', 'Dashboard::index', ['filter' => 'login']);
}); 


And to go to my dashboard:

PHP Code:

<li class="nav-item d-none d-sm-inline-block">
    <a href="<?= route_to('dashboard');?>" class="nav-link">Dashboard</a>
</li> 


What did you Try? What did you Get? What did you Expect?
