Correct URI and Route but Page Won't Load (Blank Page)

You can see the error message, do you also see the back trace?
If you can see the back trace, you can go to  the source code that the error happened.

---

When you uncomment the three lines, the output of `spark routes` does not change at all?

PHP Code:

    //$routes->get('edit_profile/(:segment)', 'Users\Members::edit_profile/$1', ['as' => 'edit_profile']);
    //$routes->get('manage_uploads/(:alphanum)', 'Users\Members::manage_uploads/$1', ['as' => 'manage_uploads']);
    //$routes->post('upload/(:segment)', 'Users\Members::upload_image/$1', ['as' => 'upload_image']); 


Here is without the comments:
