Code Igniter - Unable to load requested file after redirect
Use this pattern to redirect
redirect("controllername","function name");or
redirect(base_url().'index.php/controller/function');
Trying to load a view that doesn't exist. Load dashboard.php to your view folder. I hope it works ;))
By looking at you problem, I think this should help you out use this:
redirect(site_url().'dashboard', 'index');
