i use paypal express checkout to sell simple benefit on my website. When i am with sandbox, it works fine. But as soon as i change for live mode with real password and signature, i get systematically this error :
[ACK] => Failure [VERSION] => 123.0 [BUILD] => 21463915 [L_ERRORCODE0] => 10486 [L_SHORTMESSAGE0] => This transaction couldn't be completed
My buyer account is good and no problems to buy on other websites. I asked friends to try with their own paypal account or Credit card and they get the same issue.
I must say that i checked my script again and again but no errors. Anyway, it works fine on an other website but with an other paypal account.
Has someone already encountered this problem? thank you in advance for help.

The problem is solved. For those who find themselves in this situation, check which category you opened your PayPal account. Indeed, some categories such as online meetings require additional special authorizations. In this case, your account will refuse all transactions… Go figure why paypal does not inform you …
