Getting blank screen after paypal checkout

-- url of the page with the problem -- : snowyriverlavender.com.au/index.php/shop-here
-- HikaShop version -- :2.1.3
-- Joomla version -- : 2.5.11
-- PHP version -- : 5.4
-- Browser(s) name and version -- : IE 10.0.10 and Chrome too
-- Error-message(debug-mod must be tuned on) -- : Parse error: syntax error, unexpected end of file in /home/www/snowyriverlavender.com.au/media/com_hikashop/mail/order_creation_notification.html.modified.php on line 340

Site will not proceed to Paypal payment after final checkout stage. All checkout is as guest.
This was working fine before. I was not getting this error a few weeks ago. No changes have been made. No-one can purchase at the moment.
Can you please advise what might have caused this and how to fix?
Thanks
Viv

Hi,

The error message that you are getting is saying that your problem is coming from the changes that you have made through your "order_creation_notification" email, so can you :
- Go to "Hikashop->System->Emails"
- Save the changes that you have made through the "order_creation_notification" email in a text file
- Revert your changes through the trash icon
- And test it again ?

Thanks for the advice.
It was indeed the changes I made to the email.
Much appreciated.
