Problem with payment plugin and CURL

[mr_ixs]

I must change the line in Paypal.php
curl_setopt($ch, CURLOPT_VERBOSE, 1);
for
curl_setopt($ch, CURLOPT_VERBOSE, 0);

It looks ok. When i use sandbox work correctly. When I use normal payment didn't display the paypal button

Why do you have to change it ?
There's no difference between the sandbox and the real environment, but for the endpoint, so if it works on sandbox it should work on the real.

Could you enable PHP error reporting and paste here the log ?
