Hello. Can anyone help me get the Authorize.Net payment processor plugin up and running? I correctly entered all the required fields (Authorize.Net API login, Transaction Key, Secret Word for MD5 hash, Test Mode disabled). And I followed steps 1, 2, and 3 at the bottom of the page. To test the payment process I... 1. Go to the registration site, enroll by choosing desired membership, enter personal information, and... 2. Hit SUBMIT where... 3. The Authorize.Net registration page loads; showing my personal information and requiring me to enter my credit card information. After hitting SUBMIT again, I get the following error message displayed... 4. An Error has occurred - Error processing payment:<b></b> Please return back and try again. -Please contact webmaster: . The error log in aMember CP only shows this in the Message column: ----------------------------------------------------------------- AUTHORIZE.NET SIM DEBUG: Some other things to note: -------------------------- 1. I set up my external cron job as directed in the Advance link of aMember CP. 2. I set the URL "Relay Response" field on Authorize.Net website to: http://www.mysite.com/amember/plugins/payment/authorize/ipn.php Solving this issue would no doubt be much appreciated. Thanks!
