Flashes to generic thank you page

Greetings!
I have installed Hikashop Essential with added Styles on Joomla 2.5. I have put my thank-you page in the Return URL but it flashes to the generic page for a few seconds before going to my designated one.

Is this a bug perhaps? If not, can I somehow get round this so that it goes straight to my designated page without showing the generic one first?
Many thanks in advance
Chris

What do you mean by "it flashes" ? Could you do some screenshots with the links of each page?

Sorry, I should have been clearer. Once payment is taken, the next page is this one keepsakebooks.co.uk/index.php/choose-you...checkout/step/step-3 which is the generic page. When you put this link in your browser it will look like a nicely formatted page but it does not show like that - it is unformatted as in the screenshot below.

Where I want them to go is here : keepsakebooks.co.uk/index.php/post-payment - screenshot below. I have this URL in the Return Url box.

So on completion of payment, first the generic page is shown in unformatted form as per the screenshot for a few seconds before then continuing to the post-payment url which I want. Can I avoid this blip to the generic page? Thanks - appreciate your help.

Hi,

You will probably have to edit the file xxx_thanks.php of the payment plugin you are using.
In this file just make a redirection to the desired url.

You have to make this changes via ftp.

Thanks Xavier. Sadly I do not speak 'php'....I have located the relevant bit of the xxx_thanks.php which is shown below. Please can you tell me where to add my specific url ( keepsakebooks.co.uk/index.php/post-payment ). Many thanks indeed....

<?php echo JText::_('THANK_YOU_FOR_PURCHASE');
if(!empty($return_url)){
echo '<br/><a href="'.$return_url.'">'.JText::_('GO_BACK_TO_SHOP').'</a>';
}?>

You can use the code: Before anything else in the php file.

THAT'S IT!! THANKYOU, THANKYOU, THANKYOU.
Chris
