title: get_home_url() just returns current URL
body: <p>My problem is simple, I need a "home" link for my WP template, and the function <code>get_home_url()</code> is simply returning the current url. So if I'm on <code>"example.com/?cat=2"</code>, that's the url I get for my home button .</p>
  
  <p>Any ideas what I'm doing wrong? I'm pulling my hair out.</p>
