title: Joomla's Login doesn't work when I set variable "live_site"
body: <p>I have a Joomla 2.5.7 working with windows server 2013: <strong>SUBDOMAIN.DOMAIN.COM/name1/name2</strong></p>
  
  <p>and this is my admin: <strong>SUBDOMAIN.DOMAIN.COM/name1/name2/administrator</strong></p>
  
  <p>I've set the variable "live_site" to <strong>SUBDOMAIN.DOMAIN.COM/name1/name2</strong></p>
  
  <p>when I set the live_site, the front-end works fine, but not the back-end, I see: "component not found"
  because the component "com_login" is searching in the front-end's component folder</p>
  
  <p>when I don't set the live_site, front-end doesn't works because urls appears so: "http: // [name of the server]/bla/bla/bla", but the backend works fine because the url appears ok</p>
