I am using Version 1.1.3 and I am having the following problem.
I have setup my google checkout account, merchantID and merchandKey. When I place a test order, everything goes well. I am redirected to google.com. I finish the order via google checkout. I get a payment made email from google checkout. The order shows up in the admin section of the store as well.
HOWEVER, when I go to Capture by selecting Capture Online in the bottom right of the Order Invoice Screen… I get the following Google error:
Google Checkout: Ids are integral numbers, but you sent:
However, it does not even show what I sent? Any suggestions on how I can proceed?
