PHP problem

Hi

I am trying to use the quickinstall file of this template, but the browser is answering this to me:

Your host needs to use PHP 5.3.1 or higher to run this version of Joomla!

But the hostgator guy just told me that they are prepared to php 5.3 and he offered me this solution:

Add this code to the htaccess file

# Habilitar o PHP 5.3
AddType application/x-httpd-php53 .php

What should I do?

Thanks

You should add this code to .htaccess file as your hosting copany's guy told You .
Place this .htaccess file in the root of folder, where You would like to install our quickstart.
