Paypal shows blank page when called from redirec

-- url of the page with the problem -- : www.dreamlordpress.it/rpgmeeting/
-- HikaShop version -- : Business 2.3.4
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.4.35

Hi,

I have two different joomla sites:
www.dreamlodpress.it
www.dreamlordpress.it/rpgmeeting

All the same software (PHP, Joomla, Hikashop).

Activated Paypal payment plug-in

It works for both if I use the urls as they are.

If I redirect www.rpgmeeting.com to www.dreamlordpress.it/rpgmeeting , and call Paypal from there, Paypal shows a blank page.
This is only if I mask the URL.
If I just redirect (so I actually call paypal from www.dreamlordpress.it/rpgmeeting ) then it works fine.

How can I keep paypal usability from www.rpgmeeting.com ?

Hi,

What is the URL of the blank page ? What do you get on the screen just before that blank page ? Could you provide a screenshot ?

Hi,

Now www.rpgmeeting.org has redirect+mask (not working), while www.rpgmeeting.com has redirect (no mask, working)

Thing is rpgmeeting.org seems not going anywhere (URL remains the same), while rpgmeeting.com (actually dreamlordpress.it/rpgmeeting/) goes to paypal (there's another problem with invoices already payed but paypal actually responds).

Here's the blank page:

And here's "viewsource" of the blank page:

Hi,

How did you do the redirect exactly ?
Also, what do you have in the URL setting of the paypal payment plugin ?

Sorry for the late reply. I am taking ownership of the problem from NIcola Urbinati - he did not reply because he was waiting for info from me.

The non-working redirect is done via "Forward with masking" option at domain manager level (GoDaddy). Essentially each nameserver request replaces "rpgmeeting.org" with "dreamlordpress.it/rpgmeeting" but keeps the original URL in the browser.

Paypal URL

www.paypal.com/cgi-bin/webscr

Hi,

I did a full test on rpgmeeting.org and I was correctly redirected to PayPal at the end of the checkout:
take.ms/y8Nsh
So either you found already a solution or I didn't understand what was the problem ?

Now THIS is weird.

I have redone the exact same thing with the exact same product, and I got a blank page. There are two differences though: you used Chrome while I used Mozilla, and I see a "shipping&handling" fee that should not be there. That product is only available at "zero shipping fee".

Hi,

So I did a test with FireFox and I got the blank page too:
take.ms/gNzSa
And you can see the issue there.
FireFox refuses to load the PayPal payment page because it is in an iframe. So the issue is with the "redirect" system you use with your website URL.

One solution you could try is to add an attribute target="_blank" to the line:
<form id="hikashop_paypal_form" name="hikashop_paypal_form" action="<?php echo $this->payment_params->url;?>" method="post">
in the file plugins/hikashoppayment/paypal/paypal_end.php
so that it would open the payment page of PayPal on a new tab, avoiding the issue of having the PayPal payment page inside an iframe.
