I thought all LP shared servers were default to PHP 5.3 or so by now. Run the following test.php file:
<?php phpinfo(); ?>
and see what it reports PHP is. Is this a dedicated or VPS/cloud server?
What does your account control panel (either cPanel or LPCP) say that PHP is? There may be a control somewhere to tell it to use a specific version of PHP. Make sure it isn't set to force PHP 4.4.9. Did someone manually put anything in the /.htaccess file to set a PHP version? Is this a new account or one that's been around a while? If it's old, was something done long ago to force PHP 4.4.9?
If nothing seems to help, open a support ticket (email firstname.lastname@example.org
) and ask how to get PHP 5.3 or higher on your account.
