I use osCommerce Online Merchant v184.108.40.206 CE with the responsive based on this http://template.me.uk/234bs3/index.php
So, I have some trouble using paypal, I use the sandbox
1 - First payment in client account : "hasn't accepted yet"
Settings in paypal has been set to accept automatically
---> See Attachment 1 : the client transaction
---> See Attachment 2 : the order in the admin area in oscommerce
---> See Attachment 3 : the paypal seller money (me)
---> See Attachment 4-5-6 : Paypal Setting in os commerce
---> See Attachment 7-8 : Check information about paypal transaction
Is the transaction number of the client should be the same as the seller ? (client is 1U566944GK3544510 / Seller is 43C83949SX318715F)
When I click on details, i have this message : A problem occurred while retrieving details of the PayPal transaction. Please check the PayPal App Log for more information.
So, I go see that in paypal logs : GetTransactionDetails (Attachment 8 )
I've also tried to put the last Paypal Apps, but no way to make it works too. https://apps.oscommerce.com/fZMiN&paypal-app
Some times, when I load the paypal express module, i have this error :
The only way I have to fix it is to set the order in the module / payment section
Thanks for help Best Regards
