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");
