ok, Paypal pro is already up on my shop however it doesn't seem to be working.

it goes from step 1-3 but never finalizes the last step confirming the order, once you click on continue in step 3 it takes you back to step 1.

from there I get an error message unable to set private key file: '/home/site/public_html/shop/paypal_wpp/paypal_cert_pem.txt' type PEM (Error No. 58)

I'm not sure if this is the reason, but i am looking for someone who can get my paypal working
