hello, I have setup the latest store module (2.x) and have registered on developer.paypal.com as sandbox.paypal@mydomain.com created two accounts on developer.paypal.com vix - merchant.sandboxtesting.mydomain.com and customer.sandboxtesting.mydomain.com. Both are confirmed with balance in them. developer.paypal.com gave me two id's when i created above accounts 1) merc_19xxxxxx_biz@mydomain.com and 2) custo_17xxxxxx_cust@mydomain.com.
Now went into my dnn and logged in as host, set the payment processor as paypal, and checked the "sandbox" check box for sandbox testing. Updated the service provider email id merc_19xxxxxx_biz@mydomain.com and then also updated the admin settings for the website with the exact same info.
I have product costing $1 which I purhcase and then shop via custo_17xxxxxx_cust@mydomain.com and all goes well until I hit "pay" button which then gives me this error everytime without fails - "This invoice has already been paid. For more information, please contact the merchant"
Can anybody help me understand what am I doing wrong? what should I be doing to get ride of this error and make the setup work?
PLEASE GURU'S, any and EVERY HELP/GUIDANE is very highly appreciated. I am sure I am not the only fellow who might have hit this situation?
Please help me resolve this error, it's driving me nuts since past 2 days.
Sincerely appreciate any reply,
Thanks much in advance.
