mmsimon Posted May 4, 2011 Share Posted May 4, 2011 HELP! I have set up ajax single page checkout in my clients oscommerce site. They needed a one page checkout that worked with authorize.net. It is all working fine until I place the order. I have it in test mode but I tried live mode too. I keep getting this error. Your credit card was declined. Please try another card or contact your bank for more info. ((TESTMODE) The merchant login ID or password is invalid or the account is inactive.) I have tried everything to make this work. They are getting very impatient as I am to get this done. I'm lost. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
