Transaction Error – something is wrong.

Hi, Thank you for your plugin, I entered API signatures or credentials from two different Paypal Accounts and I made two payment tests and I received twice the following message: “This transaction cannot be processed. The merchant’s account is not able to process transactions. (Transaction Error) something is wrong.” I noticed this error after a customer tried to purchase a product on my site.. so, I called Paypal and they said that there is no problem or limitations in my Paypal accounts.. What do you think that could be the problem? I was using stripe for receiving credit card payments, but I wanted to use your plugin with Paypal for credit / debit card transactions.. unfortunately I don’t think this could be possible.. Thank you for your help, Regards Thank you for reaching out to us. Please check the following documentation to make sure you have configured the plugin correctly. https://wp-ecommerce.net/paypal-pro-payment-gateway-for-woocommerce Kind regards.
