I have purchased and installed the Prestashop paypal advanced module in my site.
My Prestashop version is 1.5.6. Module configured as per user manual.
Then i can see the paypal advanced payment method in my checkout page.
I have selected the paypal advanced and it showed the paypal creditcard iframe.
Then i filled the creditcard fields, after click on place order.
I am getting blank page in checkout page, I have missed any steps in my installation and configuration.
Kindly help me to fix this issue.
