Redirect() not working

[eluser]ywftdg[/eluser]
In my controller, I am trying to fwd people somewhere when they hit the index, I have used this in the past with no problems.

Code:

function index()
    {
        
        redirect('projects');
        
    }

But now on this project, I am getting an error when I load the site:

A PHP Error was encountered

Any ideas?
