I am getting orders in Google Checkout but they always get the following error:

We encountered an error trying to access your server at https://www.batteriesforipod.com/......nsehandler.php -- the error we got is: Sending failed with HTTP response code: 401. Response body was: Failed to Get Basic Authentication Headers

Does anyone have a solution. I did a search but nothing came up. Is there another outlet to post problems besides here?

Thanks
