need help inserting a simple page link

Hi
New to code igniter,

We just purchased a template built with code igniter. I am trying to make the link to our blog which is on a sub domain.
I found the line in views/header.php but when I change the href to the sub domain it does not redirect but give 404 error page.

Do this also need to be changed somewhere else?

Code:

<li class="gnb"><a class="mn-stores" href="blogs"><?php echo "Blogs";?></a></li>
