Paypal Payments Pro ERROR (2030)


Recommended Posts

Hello. Please bear with me, as I am pretty new to this.


I have set up a shopping cart and have installed the Website payments Pro Module.

I have set up a Paypal account, and downloaded the API certificate, and uploaded it to the directory paypal_wpp/certs/cert_key_pem.txt (although my main directory is called "ecommerce", not "catalog").


When attempting to submit an order, I have received the error ?(2030) Unable to find API certificate file.?


Does anyone have any suggestions on where to start troubleshooting??


Here's what I have for the module settings:


Enable Website Payments Pro Module

Do you want to accept credit card payments through WebSite Payments Pro?





Payment Zone

If a zone is selected, only enable this payment method for that zone.



Set Order Status

Set the status of orders made with this payment module to this value



Sort order of display.

Select Test for SandBox transactions.

The path you specified for certificate is wrong or the permission on the folder where the certificate is needs to be set.

Do one thing is place a code in the folder where you have placed the certificate.




echp $PHP_SELF




and execute that page and display the result.
