Switched to new Host - PHP Fatal Error?

[kdpz]

I am using Zencart Version 1.3.8a / PHP Version: 5.2.8

I recently switched hosts and my website will not load. I get the following error:

PHP Fatal error: Call to a member function build_deepest_level_children() on a non-object in /home/sinful80/public_html/includes/modules/pages/index/header_php.php on line 21


Does any else have this problem and now how to fix it. My host site is of no help.

Thanks
