No thank-you page after successful Authorize.net payment

Hi Sergey, I have set up my membership plans in Emerald, my PayPal and my Authorize.net plugins in Hikashop, and the Hikashop action in Emerald. Everything is working except that when the Authorize.net payment is complete, instead of displaying the following Thank You page as configured in Hikashop's Authorize.net settings:

http://www.psartconnection.com/thank-you-for-your-payment

It instead displays an empty page with this link:

http://www.psartconnection.com/index.php?option=com_hikashop& ;ctrl=checkout&task=notify&notif_payment=authorize&tmpl=component&lang=en&Itemid=257

Itemid 257 is the Hikashop menu for my Membership plans: http://www.psartconnection.com/psac-memberships

Earlier today you helped me redirect the link in yellow on the Subscriptions History page:

http://www.psartconnection.com/component/emerald/?view=emlist& ;Itemid=257

to the Hikashop membership plans page, per this forum post: http://www.mintjoomla.com/support/community-forum/user-item/4027-brettvorster/52-emerald-9/4361-hikashop-walkthrough.html

It looks like the intention was that after the Authorize.net payment, customers would end up on the Emerald version of the Memberships page, but with the redirect in place, it's not going to the Hikashop list as expected.

1. Can you help me solve the empty page problem?
2. Is it possible to send successful payers to the Thank You page I specified in the Hikashop Authorize.net settings instead?

Help! I need to resolve this so that I can launch my website and make some money!

Toolie
