This is what customer is getting:
When I get to page to put in my credit card # This content cannot be displayed in a frame
To help protect the security of information you enter into this website, the publisher of this content does not allow it to be displayed in a frame.
I tried this fix below:
Edit the file plugins/hikashoppayment/paypal/paypal_end.php and change the line:
<form id="hikashop_paypal_form" name="hikashop_paypal_form" action="<?php echo $method->payment_params->url;?>" method="post">
to:
<form id="hikashop_paypal_form" name="hikashop_paypal_form" action="<?php echo $method->payment_params->url;?>" method="post" target="_blank">
But then the popup blocker blocks it and it does not work. Several customers are experiencing this.
