codeigniter 3.0 custom 404 not found error page

Question

My problem is about custom error pages after upgrading to Codeigniter 3.0.

I used to have a Errors controller which handled 404 error page of the websi

Answer 1

In Codeigniter 3, instead of calling show_404(), I just redirected to the custom error controller function.

e.g. for the above scenario

if (404 condition...) {
    redirect("my404");
}
