Question

I keep getting the following error when trying to submit a sandbox payment through my PayFlow Gateway:

Error: There was a problem processing your request. Please press the

I’m using the following code to generate my PayFlow Gateway, but I just can’t get it to work.

/* PayPal Payments Advanced */

$PF_USER        = 'my_user';
$PF_VENDOR  = 'my_vendor';
$PF_PARTNER     = 'PayPal';

Your help is appreciated!

I had to explicitly set my Firefox privacy settings to “Allow” third-party cookies. Doing this made the error message go away. I didn’t have this problem on Safari.
