Fix an anchor issue

@Mekaboo,

I need to see what anchor value is being displayed on the page. Is it something like... https://yoursite.com/index.php/chat/index

If so, then try removing the index and see if that works. Like this <?= anchor('chat','Chat');?>

Also, I noticed that you didn't load the url helper ( https://www.codeigniter.com/user_guide/h...elper.html )
