Ah, ok. Actually you just need to modify this line:
$style_side="";$tbopen="";$tbclose="";
You'd change that to:
$style_side="left";$tbopen="";$tbclose="";
As for what it's displaying. That's a bug with 7.1. You need to add one more line of code to it. Right before this:
include("/***/***/***/ubbt/languages/english/generic.php");
Add this:
include("/***/***/***/ubbt/languages/english/portal_islands.php");
