this depends on the type of hosting you have. If it is shared hosting then the host support may have to do it for you. However some hosts make it possible to upgrade php to 5.3 in the cPanel. Others (such as hostgator) make it possible to switch to php 5.3 by adding to the .htacess file this:# Use PHP 5.3
AddType application/x-httpd-php53 .php
Check with your hosting support :cheesy:
