Upgraded... Problem with templates.

Hello, we just upgraded our Zen Cart and are now getting this error on the shop's home page:

Fatal error: main() [function.require]: Failed opening required '' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/user/public_html/shop/includes/templates/seasidekites/templates/tpl_index_default.php on line 33

We dearly need some assistance with solving this quickly, any help would be greatly appreciated.

Version 1.2 templates do not work with 1.3.0.2 .

You will spend more time tracking down errors than you would if you simply grabbed a copy of the new template default or another 1.3 complatible template from the downloads area and modifying it to match your old template.

Thank you Tina. ;)
