Invalid Configuration. This transaction cannot be processed error

This is exactly my issues when I contacted Paypal about the errors message from trying to check out with a cc and I get the error "Invalid Configuration. This transaction cannot be processed due to an invalid merchant configuration." on another thread it says to contact paypal ad when I do they directed me to enter  a Third Party Permission Username

Hi,

Hi

The problem seems to be related to your PayPal Pro merchant account configuration.

You can check the error code information on this page:

10500  - error code
Invalid Configuration 
This transaction cannot be processed due to an invalid merchant configuration. 
Occurs when you have not agreed to the billing agreement.

10501  - error code
Invalid Configuration 
This transaction cannot be processed due to an invalid merchant configuration. 
Occurs when the billing agreement is disabled or inactive.

Please make sure that you have enabled and agreed to the billing agreement option under PayPal account.

Hope this help. Inform us if issue persist.

Thanks.

I am having the same problem.  I need a third party api username.....

This is really getting aggravating:(
