i created an item (using easy populate advanced). I do not see a google checkout button, but i do get a checkout button and Paypal express checkout.

However, when i click the checkout button or the paypal express button, i get "the webpage cannot be found" error message (HTTP 404 not found).

The URL showing in the address bar is "https://mysite.com/zencart/index.php?main_page=checkout_shipping" for checkout, and "https://mysite.com/zencart/ipn_main_handler.php?type=ec" for paypal express.

Other than these problems, of course is the "google checkout" button not showing (I already installed the plug-in files).

Can someone please help?
Thanks.
