I currently have the style Smartblue, and am trying to install the vB[3.5.1].Invites.System. However, I am stuck at the part in the readme where it says:

In template(s) navbar
FIND

<if condition="$show['registerbutton']">

REPLACE WITH

<if condition="$show['registerbutton'] AND !$vboptions['invites_reg_only_by_invite']">

Where can I find that. I dont seem to see it.
Here is the code for navbar for Smartblue:

<script type="text/javascript" language="JavaScript">
<!--
function log_out()
{
  // You can change 30 and 0.3 to suit your 'tastes' :)
  bo = document.getElementsByTagName('body');
  bo[0].style.filter = 'Alpha(opacity="30")';
  bo[0].style.MozOpacity = '0.3';
  bo[0].style.opacity = '0.3';

  if (confirm('$vbphrase[sure_you_want_to_log_out]'))
  {
    return true;
  }
  else
  {
    bo[0].style.filter = 'Alpha(opacity="100")';
    bo[0].style.MozOpacity = '1';
    bo[0].style.opacity = '1';

    return false;
  }
}
//-->
</script>
