Zen Cart does not work properly with PHP 5.3, until you install the patch for this. See PHP 5.3 Support.

Important moderator note:
**UPDATE: IF YOU ARE READING THIS, THEN YOU NEED TO UPGRADE TO A NEWER VERSION OF ZEN CART!!!!!!!

Merely applying the patch is ONLY a temporary bandage, and does not properly secure your site.
And will not protect you for PHP 5.4 if you wait that long.
So UPGRADE NOW!**

If you are still getting those messages after applying the PHP 5.3 patch, then you didn't apply all the files in the patch to the correct locations.

@magneod

If that's from your includes/application_top.php file, it could be your problem. That comes from the file that should be in your zc_install/includes folder.
