I keep getting the error

Quote: › Your server returned no data in its response; Checkout requires data of type merchant-calculation-results in response to merchant-calculation-callback

from my google checkout account. The responsehandler_gc.php doesn't seem to be working. I uploaded it in binary mode, set it correctly as the api callback, chose XML.

What am I missing???

Thanks.

What is your domain so I can take a look at it? Other then that message on the google side does everything appear to be working on your Joomla/virtuemart site?

Here is the site
http://www.molberi.com/web/

I'm pretty sure everything else is working.

Although, on a side note, I fixed an issue with the coupons. Whenever I would submit an order to google checkout with a coupon in the cart google would throw that "Oops..." error. Google seems to want every item(even coupons) to have a weight, so I modified your googleitem.php file to have a default weight of 0lbs. Then it worked. I didn't see anything else in the forum about that problem, so maybe that was just me.

Anyway, my current issue is with responsehandler_gc.php.

Thanks.

When I try to access any files in the callback directory through the browser it prompts me for a username and password.

Do you have extra security setup? Do you get this error when you disable it?
